Introduction to Traceable™ Products

Fisher Scientific™ Traceable™ products include timers, stopwatches, clocks, data-logging thermometers, bench thermometers, differential

thermometers, printing thermometers, humidity meters, monitoring/alarm humidity meters, barometers, as well as a range of everyday

measurement lab tools.

All of these Traceable™ products are provided with a Traceable™ Calibration Certificate from an ISO/IEC 17025:2005 (1750.01)

calibration laboratory.

Thermometer, timer, and humidity certificates are accredited by the American Association for Laboratory Accreditation (A2LA).

The supplied Traceable™ Certificate indicates that the product is traceable to standards provided by the National Institute

of Standards and Technology (NIST), a U.S. Government agency within the Commerce Department.

The Traceable™ Certificate complies with ANSI/NCSL Z540-1.

The Traceable™ Certificate includes all of the information to meet today’s stringent accreditation demands, government specifications, and ISO 9000 requirements.

This information includes serial number, certificate number, model number, calibration test equipment, equipment serial number, equipment calibration due date, NIST test number, unit

accuracy, uncertainty, unit test conditions, test points, individual unit’s specific test date, unit’s next calibration due date, tester’s name, and signature of the metrology manager.

Each Traceable™ product is individually serialised, calibrated and certified. An individually serialised Traceable™ Calibration Certificate provides you with the assurance that an independent

auditor has checked the methods, procedures, testing, technique, and record-keeping practices of the calibration testing laboratory. The American Association for Laboratory Accreditation

(A2LA) is widely recognised internationally through bilateral and multilateral agreements and through its participation in International Laboratory Accreditation (ILAC) and Multilateral

Recognition Agreement (MRA). Through A2LA Accreditation, Traceable™ Certificates are internationally recognised by Accreditation Agencies and Services in over 75 countries throughout

Europe, the Middle East, North America, South America, Asia, and Africa. There is no need to have the units calibrated locally before use as all European governing bodies fully accept and

recognise the Traceable™ Certificate of Calibration.

Finally, all products are produced under ISO 9001, certified by DNV (Det Norske Veritas), and supplied by an ISO 9001 Quality Certified Company. This quality certification provides you with

the assurance that you will receive only the finest and most reliable products.

ISO 9001 Certification is a worldwide recognition of the highest possible quality for innovative electronic products and ensures that every item is checked and rechecked for superb

laboratory performance time after time. As already described these products are manufactured to the highest standards and undergo rigorous quality assurance and testing procedures to

ensure that they deliver on our promise of quality, reliability and value.

Ion-selective electrode measurement has never been this easy. And with dual-channel capability, there is no need to recalibrate every time you switch from pH to ISE measurement. The XL250 displays the ion name right on the measurement screen so you’ll never have the wrong ISE curve.

Addition/subtraction methods are almost foolproof. The XL250 prompts you through the method steps, allowing easy entry of volumes and concentrations, providing you with the sample concentration without tedious paper calculations.

» Dual-BNC channels; use them for pH or mV or ion selective measurement – you decide

» Accepts any pH, ORP, or ion selective electrode with BNC connector

» View independent electrode slope in each channel and each range at a glance

pH Electrodes For Virtually Any Sample Type

Fisher Scientific™ accumet™ Electrodes

When selecting a pH system, choose your meter based on what features you need, i.e. resolution, output, memory, etc. Choose the corresponding pH electrode for your meter based primarily on your sample type and conditions, i.e. wastewater with sulfides, room temperature, student use, 5 days/week, etc.

Take a glance in this catalog and you will find variety of pH electrodes to choose from. While many electrodes might be work adequately for a particular application, not all will perform equally or last as long as others. Usually in situations in which a pH electrode “didn’t last long”, the electrode is not matched well for the application resulting in poor performance, and ultimately failure. Understanding the different electrode options that are available and knowing how to use them to your advantages is a critical step to getting the most out of your pH measurement system.

The following guide is designed to help you understand the ABC’s of electrode selection.

The ABC’s Of Electrode SelectionCombination Or Half-CellThere are two components within a pH electrode system. A pH indicating (or sensing) electrode develops a potential dependent on the pH, and the reference electrode which provides a constant potential to completes the electrical circuit. Combination electrodes have both the indicating and reference electrodes “combined” into one electrode. Alternatively, separate half-cell electrodes can be used. Since reference electrodes often outlast sensing electrodes, replacing indicating electrodes can mean lower replacement costs than replacing an equivalent combination electrode.

In practical terms, nearly all electrodes used today are combination electrodes. There are many reasons including; many pH meters require an adapter to accept half-cell electrodes, handling multiple electrodes is un-desirable (or impossible with small samples!), half cells don’t have built in ATC and therefore require a third electrode for temperature compensation, the complexity of diagnosing electrode problems and most of all, the reduced cost and performance of today’s combination electrode designs.

Verdict: Use a combination electrode unless the method you must follow calls

for half-cells. You’ll have many more choices available to you. Combination

cells may or may not have a temperature sensor built-in.

Glass Or Plastic BodyIt probably goes without saying, but if an electrode literally breaks into pieces, it is useless and can not be repaired. Combination glass and combination

Indicating half cell (13-620-187)

Combination electrode (13-620-299)

Reference half cell (13-620-658)

plastic electrodes use an indicating electrode with a glass sensing bulb on the end. This is important for several reasons. First, plastic electrodes are not immune from breakage. Second, if an electrode breaks it will likely be at the tip, not the body itself. A plastic electrode with little to no bulb protection defeats the purpose of a plastic electrode in the first place.

To decide on which to use, let us look at the advantages and disadvantages of each, starting with the glass body electrode. Glass electrodes are easier to clean and maintain since they can tolerate just about any solvent and inorganic material (with the exception of HF!) and can handle higher temperatures quite nicely – typically to 100 °C. The fact that glass electrodes also have a glass sensing bulb is also an advantage. Since the seal that combines the bulb to the body is similar material, it is one less thing that can go wrong during measurement and doesn’t become the source of junction potential as it does in plastic electrodes. This is especially important consideration for applications that have repeated and extreme heating and cooling – the expansion and contraction that occurs is handled much better by glass electrodes. The downside of glass electrodes is fairly easy – they are generally more expensive then plastic, and they have a greater potential for breakage.

Plastic electrodes are less expensive than glass equivalents and can usually take much abuse in the lab and in the field. Most electrodes with built-in temperature compensation elements are plastic due to the complexity in manufacturing them. As a result, they are most popular with field and portable meters, but can also be used in laboratory environments (such as 13-620-631). To protect the glass sensing bulb, many plastic electrodes use an integral housing that limit the bulb exposure, but often can be difficult to clean.

Verdict: Glass electrodes are definitely worth the upgrade if you have

significant temperature fluctuations. If bulb breakage is a concern, consider

Fisher Scientific™ accumet™ accuTupH electrodes with thick glass bulbs! If you

want ATC built-in to your electrode, expect to settle for plastic.

Refillable Or Non-Refillable (Gel)All pH electrodes use/leak solution. Refillable electrodes do so more quickly, and can be replenished when they require more filling solution. Gel filled electrodes do so very slowly and when they run out or the gel is no longer flowing, can not be replenished and must be replaced.

Refillable electrodes are generally more expensive than gel-filled equivalent electrodes but respond much faster. They also last longer, because the filling solution can be replaced indefinitely; however the periodic addition of filling solution that is required also happens to be the main disadvantage. Another downside is that when the filling hole is left open for an extended period, dried salt may be left behind which often involves cleaning. The act of refilling and opening and closing the fill hole with Fisher Scientific™ accumet™ electrodes is extremely easy due to the patented filling mechanism. It takes just seconds to open the hole and a few seconds more to fill the probe.

Gel-filled electrodes are less expensive, require less maintenance, and are usually plastic. High quality gel formulations have also extended the once limited shelf-life in recent years.

Verdict: Refillable electrodes are usually worth the extra maintenance –

especially if it’s a Fisher Scientific™ accumet™ electrode.


49

Single Or Double-Junction (Tris Compatible)

This decision is extremely important and should not be overlooked. If you will be measuring samples that have sulfides, proteins, heavy metals, TRIS, or anything that might react with silver, or if you will be testing samples that are unknown, use a double-junction electrode. Calomel electrodes would also be suitable but have fallen out of favor due to mercury content and regulations that ban shipments of them in specific states in the US. Single-junction electrodes are less expensive, but offer no other advantages. If you use a single-junction electrode in a solution with TRIS, it’s just a matter of time before it fails.

Verdict: If you will only measure drinking water, you can save money by

using a single-junction pH electrode. If you have TRIS, sulfides, proteins,

heavy metals or are measuring samples that are unknown, look for a

Fisher Scientific™ accumet™ electrode with a purple ring – indicating that

is it compatible.

The single-junction electrode on the left has a black, clogged junction and is no longer responsive.

Next to temperature, pH is quite possibly the most common laboratory measurement today. It crosses over many disciplines from water/wastewater, R&D, environmental, chemical & life sciences, and an endless number of industrial applications.

The pH or power of Hydrogen, is the degree of acidity or alkalinity of a solution based on the hydrogen ion activity, represented by the equation:

pH = -log [H+]

Stated mathematically, pH is the negative logarithmic value of the Hydrogen ion. As it is based on a log scale, each pH unit represents a factor of 10, so a solution with a pH of 5 is 100 times more acidic than pH of 7.

Here are examples of pH in a few common industrial and household products.

Litmus paper can be used for rough pH measurements, but for highest accuracy a potentiometric system using a pH meter and pH electrode is used. The electrode is sensitive to H+ ions, which create a small voltage potential, which is converted to a pH value by the pH meter. Electrode behavior is described by the Nernst equation:

E = Eo + (2.3 RT/nF) log aH+

E is the measured potential from the sensing electrode, Eo is related to the potential of the reference electrode, (2.3 RT/nF) is the Nernst factor and log aH+ is the pH. The Nernst factor, 2.3 RT/nF, includes the Gas Law constant (R), Faraday’s constant (F), the temperature in degrees Kelvin (T) and the charge

of the ion (n). For pH, where n = 1, the Nernst factor is 2.3 RT/F. Since R and F are constants, the factor and therefore electrode behavior is dependent on temperature.

The pH electrode system consists of two half cells: a pH indicating electrode, which develops a potential dependent on the pH of a solution; and a reference electrode, which provides a constant potential and completes the electrical circuit. Using separate pH indicating and reference half cells allows you to select each cell without compromise, tailor the system precisely to the sample’s nature, and achieve good accuracy. It can mean lower replacement costs too, since usually only one of a pair is broken. For ATC, a third electrode is required. Nevertheless, the combination electrode – an indicating half cell and a reference half cell joined co-axially – is by far the most common choice for the convenience and compactness it offers. Some combined electrodes also offer built-in ATC for added convenience.

Temperature CompensationIn a perfect pH electrode – one that measures zero mV at exactly pH 7 – there is no temperature effect on the electrode sensitivity at pH 7 regardless of temperature change. While pH electrodes are not perfect, errors related to temperature are negligible near pH 7, and can be disregarded. As a rule however, the further from pH 7 the solution is and the greater the temperature changes, the greater the expected measurement error due to changes in the electrode’s sensitivity. For most electrodes, the error is approximately 0.003 pH/ºC/pH away from pH 7.

Consider a pH meter that was calibrated at room temperature (25 ºC) and measures a sample at pH 4 at 5 ºC,Temperature difference : 25 ºC - 5 ºC = 20 ºCNumber of pH units away from neutral : 7 pH - 4 pH = 3 pH unitsTotal error : 0.003 x 20 x 3 = 0.18 pH

pH meters that incorporate Automatic Temperature Compensation (ATC) are able to overcome this error.

Q: So why does my pH 10.00 buffer read as 10.06? A: ATC or not, temperature influences the pH of all solutions. While pH 10.00 buffer is certified to 10.00 at 25 ºC / 77 ºF, at 20 ºC / 68 ºF which is often room temperature, it is actually 10.06.

To understand the pH/temperature relationship, we need to look at two main processes; Calibration & Measurement.

Calibration: Meters have a buffer/temperature look-up table stored into memory for every pH buffer that the meter can calibrate to. For example, when calibrating with a pH 10 buffer that is 20 ºC, the meter knows to calibrate to a value of 10.06 when calibration is performed. Had the temperature of the buffer been 25 ºC, the meter would calibrate instead to 10.00. Using a temperature probe during calibration allows best accuracy as the meter is able to calibrate to the most appropriate pH value.

Measurement: As temperature changes, the pH electrode responds slightly differently. Since this change is predictable, the meter is able to make the appropriate adjustment. The meter senses the temperature and applies the appropriate electrode slope (mV per pH unit) for that temperature. For example, if the temp is 25 ºC, the instrument uses 59.16 mV for each pH unit. If the temperature is 20 ºC, the meter uses 58.16 mV for each pH unit. Using a temperature probe during measurement allows best accuracy as the meter is able to correct for changes in electrode response due to temperature. Note: Temperature compensation only corrects for the change in the output of the electrode, not for the change in the actual solution pH. As such, the AB15 will always display the actual pH of the solution at the current temperature.

A Practical Approach To Achieve Best Results

About pH, ORP, And ISE Measurement

About pH, ORP, And ISE Measurement

pH Standardization BuffersBuffers – solutions of known pH value – allow adjustments to the meter/electrode system to reflect accurate measurements. Certified accurate buffers are available as ready-to-use color coded solutions, concentrated solutions, capsules and prepackaged salts. All have the special characteristic of resisting pH change upon dilution or acid/base contamination. For best accuracy, use a minimum of two-point standardization; first with a buffer value close to the electrode system’s zero potential (typically pH 7); and next with an acid or base buffer whose value brackets the expected pH value of the sample. Microprocessor-based meters may permit additional calibrations – up to five points in some models. For best accuracy, perform calibration with ATC at the same temperature as the expected samples.

ORP MeasurementOxidation-Reduction Potential (ORP) or “Redox” measurements are used to monitor chemical reactions, to quantify ion activity, or to determine the oxidizing or reducing properties of a solution. ORP is a measurement of the total electrical potential of a solution – a sum of all oxidation and reduction reactions.

ORP electrodes measure the voltage across a circuit formed by the measuring metal half cell and the reference half cell. When the ORP electrode is placed in the presence of oxidizing or reducing agents, electrons are constantly transferred back and forth on its measuring surface, generating a tiny voltage. ORP is expressed as +/- mV, and can be measured by using the millivolt mode of any pH meter with an ORP electrode.

Like pH, an ORP electrode system consists of a sensing and reference electrodes. For ORP, the indicating electrode is metallic – usually platinum, gold, or silver.

ORP varies with temperature, but unlike pH, it is not completely predictable and therefore, ATC is not used. Constant temperature is best for monitoring ORP.

In principle, ORP measurements should not require standardization; in practice however, it may be necessary to check the system against standards of known potential, as described in ASTM Method D 1498.

ORP is also useful in pool water treatment as an indication of sanitation in relation to free chlorine. ORP technology has gained recognition worldwide and is found to be a reliable indicator of bacteriological water quality. The table below illustrates the Kill Time of E.Coli bacteria as a function of ORP value. With a value of 600 mV, the life of the bacteria is almost 2 minutes; at 650 mV it reduces to 30 seconds. Above 700 mV the bacteria is killed within a few seconds. It is therefore necessary for the water to have an ORP value of at least 700 mV to ensure good water quality.

ORP value also depends on the pH of pool water. The pH of the pool water has to be maintained at the optimum level between 7.2 and 7.6 pH by dosing appropriate chemicals. If the pH of the swimming pool water is acceptable and the ORP value is below 700 mV, hypochlorite or other oxidizing chemicals should be added.

Common ORP applications include the treatment of industrial wastes, study of biological systems, oxidation of cyanide, bleaching of pulp, manufacture of bleach and reduction of chromate wastes.

ISE MeasurementIon-Selective Electrodes (ISE) respond to a particular ion in solution because of the characteristics of the electrode’s sensing membrane. Ideally, the ISE develops an electrical potential which is proportional to the concentration of the ion for which the membrane is selective. The most widely-used ISE is the glass-membrane pH electrode (selective for hydrogen ion).

When an ISE – the indicator electrode – and a reference electrode are placed in a solution and connected to a pH/ion meter, they form a potentiometric cell. At equilibrium, the meter measures the potential difference between the ISE and the reference electrode. This potential is proportional to the activity of the ion of interest.

The table below gives theoretical slope values at 25 ºC:

Although ISE’s are most often measured by direct analysis, some sample preparation is required. Normally, an ionic strength adjuster must be added equally to samples and standards. Then, standards must be prepared which are used to calibrate the meter, or to construct a calibration curve (by plotting the electrode’s output in mV vs. the log of concentration). Sample concentration can then be read directly from the meter or calibration curve.

Incremental methods can reduce errors caused by temperature variations, complex matrices, and complexation. They’re also useful for applications where only occasional samples are analyzed. Incremental methods include: 1) Known Addition; 2) Known Subtraction; 3) Analyte (Analate) Addition; and 4) Analyte (Analate) Subtraction.

Ion-selective electrodes can also be used to detect the endpoint of a titration. The ISE can be selected to monitor either the addition of titrant or the depletion of analate. The electrode potential is plotted vs. the volume of titrant added. The volume corresponding to the equivalence point is determined from the graph, and used to calculate sample concentration.

A number of metallic electrodes are also used in titrations. Dual platinum wire and plate electrodes, are used with pH meters and titration instruments in dead-stop and amperometric titrations; and silver billet electrodes are the choice for silver and halide titrations.

The ion meter/electrode system must be standardized by immersing the electrodes into solutions having a known concentration of the ion of interest. Stock ISE standards are available in a variety of molar, ppm, and percent concentrations. Calibration is typically done using at least two points that are 10 fold apart, such as 1 and 10 ppm. An ionic strength adjuster is required to eliminate interference from other ions. Since some ISE’s have a restricted pH range, a pH adjustment solution may also be necessary. Other special reagents and solutions are available for specific applications.

pH Electrode OffsetA perfect pH electrode under ideal conditions, when placed in pH 7.00 buffer at 25 ºC, will produce 0 mV. The difference between 0 mV and the electrode’s actual mV reading is called the offset error, which usually becomes problematic when it is more than ±30 mV or about ½ of a pH unit.

pH Electrode SlopeA perfect pH electrode under ideal conditions at 25 ºC, produces a slope of 59.16 mV per pH unit. For example, an electrode with 0 mV offset should read mV value of 177.48 mV when placed in a pH 4.01 solution. The slope is calculated as (177.48 mV – 0 mV) / 3 pH = 59.16 mV/pH. The difference between this perfect slope reading and the electrode’s actual reading is called the slope error. These theoretical values are not always achieved, even with brand new electrodes. The slope of most new pH electrodes should fall between 92 % and 102 % of 59.16 mV.

Normal AgingAs electrodes are used or stored for long periods they can undergo changes in performance. The electrode offset and slope can be monitored to evaluate these changes. Periodic calibration is usually adequate to correct for these changes. If an electrode is able to be calibrated and reads accurately in certified standards, is stable, is responsive and repeatable, it is still considered functional and may be used indefinitely although it no longer meets “new” electrode specifications with regards to offset or slope.

How to check your pH electrode – including slope and offset:1. Clear/reset any existing calibration stored in your meter then select the

millivolt (mV) mode of your pH meter

2. Using a pH electrode, obtain mV readings of two fresh calibration buffers (i.e. pH 4.0 and pH 7.0 are best)

3. Determine the net mV change

4. Determine the net mV change per pH unit change and compare using the chart below. For example, at 25 ºC: pH 4 = 170.5 mV, pH 7 = -3.4 mV: Net change = 170.5 mV - (-3.4 mV) = 173.9 mV. Since pH 4 and pH 7 are 3 pH units apart, using the chart below, 98 % = Very Good

5. The offset can be determined by observing the mV reading with your pH electrode in pH 7 buffer. The closer to 0 mV the better. A mV more than 30 mV from 0 may be problematic.

6. Also take notice of the electrode response time – the faster, the better. Don’t expect an economy gel electrode to respond as fast as a high performance glass refillable electrode, but note that a great slope alone is not meaningful if the electrode takes 2 hours to stabilize.

Common Symptoms/Cause (Remedy)• No Response, All Buffers Or Samples Read The Same pH –

Usually pH 7.00 Or 0 mV Broken sensing bulb or wiring problem (replace electrode), probe not

connected to input (verify correct channel selection when using multiple-channel meters), probe is not in contact with sample (remove electrode storage bottle or rubber bulb guard), meter automatically has frozen reading (verify that the hold feature or auto read feature is set to off when using meters with this feature, usually by pressing measure or read.)

• Slow Response With Excessive Crystallization Inside Probe Of Refillable Electrodes

Electrolyte flow clogged from supersaturated electrolyte (“flush & fill” by remove the filling solution through the fill hole with a syringe or by shaking it upside down. Repeatedly flush and rinse the reference cavity with clean, 60-80 ºC water to dissolve crystals until removed. Replace filling solution and apply gentle pressure to the filling hole. Re-hydrate electrode in storage solution or pH 4 buffer), (ensure fill hole is in open position). To prevent this in the future, ensure that the re-fill hole is closed when electrode is not in use.

• Slow Response Due To Clogged Junction-Usually With Single-Junction Electrodes

Reaction with silver such as silver sulfide formation or protein deposits which causes a dark spot on the ceramic reference junction (For protein layers prepare a 1 % pepsin solution in 0.1 M of HCl and soak the reference junction for one hour in this solution. Rinse the electrode with distilled water. Alternatively, heat a diluted KCl solution to 60 to 80 ºC. Place the sensing part of the electrode into the heated solution for about 10 minutes. Allow the electrode to cool in some unheated KCl solution.

• Dried Salt Deposits Present Electrolyte residue deposited on electrode surface – often with new

electrodes or periods of non-use. (simply dissolve the deposits in warm tap water followed by a brief soak in pH 4 buffer).

• Slow Response, Noisy, Unstable, Or Erratic Readings Sensing bulb dry or dirty (clean electrode with mild detergent & warm water

and re-hydrate electrode), temperature may be changing rapidly or electrode may be thermally shocked (allow electrode to reach sample temperature), sample may be non-aqueous (take 30 second readings and soak in pH buffer for one minute between measurements).

General Rules And Tips• When using refillable electrodes, open the fill hole during calibration and

measurement – but remember to close it afterwards when finished!

• The level of electrolyte in the outer cavity of refillable electrodes should be kept above the level of the solution being measured to prevent reverse electrolyte flow.

• The electrode need only be immersed far enough to cover both the glass pH sensing bulb and reference junction to obtain accurate readings.

• Electrodes perform best when they are hydrated. However, if they dry out they can be reconditioned to normal performance again. Soaking in electrode storage solution helps to optimize and re-establish the thin hydration layer on the sensing bulb that is critical to pH measurement.

• Rinsing the electrode with deionized or distilled water between samples is fine, but storage in deionized or distilled can be detrimental as it will rob critical ions from the sensing bulb. Also, avoid wiping or touching the sensing bulb to maintain the hydration layer and producing any electrical charge.

• Moving or touching the electrode cable may result in unstable readings due to the high impedance (resistance) of the pH glass membrane and introduce noise.

• To eliminate temperature errors associated with the electrode, manual or automatic temperature compensation (ATC) should be used for best accuracy. Since temperature changes pH, the sample temperature should always be noted with pH readings. i.e.) Record results as “pH 8.43 @ 23.2 ºC”, instead of “pH 8.43”.

• Always use fresh pH buffers for calibration. Excessive air exposure and sunlight an alter the buffers value – especially pH 10.00 buffers which is particularly susceptible to drift.

Resistivity, Conductivity, and Salinity UnitsThe basic unit of conductivity is the Siemens (S), formerly called the mho. Since cell geometry affects conductivity values, standardized measurements are expressed in specific conductivity units (S/cm) to compensate for variations in electrode dimensions. Specific conductivity (C) is simply the product of measured conductivity (G) and the electrode cell constant (L/A), where L is the length of the column of liquid between the electrode and A is the area of the electrodes.

C = G x (L/A)

Resistivity is simply the reciprocal of conductivity: conductivity = 1/resistivity. In practice, resistivity units are used when describing ultra pure water such as deionized or reverse-osmosis water. Conductivity units are used for water ranging from drinking water to brackish water. Salinity units are reserved for the highest concentrations expressed as parts per thousand (ppt) or more commonly % concentrations of salt, such as 3.5 % sea water.

Total Suspended Solids (TSS) and Total Dissolved Solids (TDS)Suspended Solids measurements are traditionally determined by filtering a measured volume of water – usually 1 liter. Solids captured by a filter are deemed “suspended solids”. The water that passes thru (filtrate) is oven dried and the residue that remains is called “dissolved solids”. Both are usually measured as mg/L or ppm. Unfortunately, drying of the filtrate to complete evaporation is a long process and requires heating. TDS (conductivity multiplied by a TDS factor) can be used as a quick, inexpensive alternative method. TDS as measured with a conductivity meter will correspond to the dissolved ionic content that is often a useful approximation for the total dissolved material.

There are limitations when using TDS. First, a TDS factor used is salt specific so if there are multiple or unknown salts in solution, it’s nearly impossible to determine the ideal factor to use. Second, since ionic concentrations are not linear, the TDS factor changes with concentration. Also, TDS is not preferred for low measurements.

Electrical Conductivity (EC) meters measure the capacity of ions in an aqueous solution to carry electrical current. As the ranges in aqueous solutions are usually small, the basic units of measurements are milliSiemens/cm (mS) and microSiemens/cm (μS).

Conductivity MeasurementThe principle by which instruments measure conductivity is simple – two plates are placed in the sample, a potential is applied across the plates, and the current is measured. Conductivity (G), the inverse of Resistivity (R) is determined from the voltage and current values according to Ohm’s law.

G = I/R = I (amps) / E (volts)

Since the charge on ions in solution facilitates the conductance of electrical current, the conductivity of a solution is proportional to its ion concentration. However, conductivity may not correlate directly to concentration. The graphs below illustrate the relationship between conductivity and ion concentration for two common solutions. Notice that the graph is linear for sodium chloride solution, but not for highly concentrated sulfuric acid.

Temperature Compensation and CoefficientConductivity is greatly influenced by temperature. Most fluids increase in conductivity as temperature increases. Most ionic solutions will increase about 2 % for each 1 ºC increase. Unfortunately, this temperature coefficient (TC) is not always. In the case of high resistance water it can be closer to 5 % or so per ºC.

Many instruments adjust the conductivity value based on a TC and display a value that is said to be corrected or normalized to 25 ºC. The meter will automatically make corrections to the reading and display a value as if the sample was 25 ºC, no matter what the actual temperature is. Some instruments use a fixed TC of 2.0 % per ºC. Let us consider a meter that uses 2.0 % TC to measure a 1413 µS standard at 25 ºC (77 ºF). If the standard is warmed to 30 ºC (86 ºF), the meter applies a correction of 5 degrees x 0.02 % x 1413 µS = 141.3. Without correction (0.0 % TC) the actual value of a 1413 µS standard of KCl at 30 ºC (86 ºF) is 1548 µS. As the meter corrects for temperature, it displays a value of 1548 µS minus 141.3 µS = 1407 µS. When the sample cools to 25 ºC, it will again read 1413 µS as no correction is applied. Although conductivity cell response is immediate, temperature corrected values will fluctuate as the temperature measurement stabilizes. Advanced meters offer adjustable TC’s, usually from 0.0 % to as much as 10 % per ºC.

Calibration and MaintenanceConductivity systems should be calibrated to certified solution standards before using. When selecting a standard, choose one that has the approximate conductivity of the solution to be measured. Unlike pH, conductivity cells generally change less over time and therefore do not require as frequent calibration.

A polarized or fouled electrode must be cleaned to renew the active surface of the cell. In most situations, hot water with a mild liquid detergent is an effective cleanser. Alcohol easily cleans most organic matter, and chlorine solutions will remove algae, bacteria or molds. To prevent cell damage, abrasives or sharp objects should not be used to clean an electrode. A cotton swab works well for cleaning but care must be taken not to widen the distance of cell.

2-Cell Vs. 4-CellMost conductivity meters use a 2-cell electrode. The electrode surface is usually platinum, titanium, gold-plated nickel, or graphite. The 4-cell electrode is more expensive and uses a reference voltage to compensate for any polarization or fouling of the electrode plates. The reference voltage ensures that measurements indicate actual conductivity independent of electrode condition, resulting in higher accuracy.

Both table salt and sugar dissolve easily in water. However, since

sugar molecules don’t dissociate there is no charge and they can’t

be detected with an electrical conductivity/TDS meter.

Advanced Meter Features To Consider• Adjustable TDS Conversion Factor

When a solution does not have a similar ionic content to natural water, the ability to adjust the TDS conversion factor will enable improved accuracy.

• Adjustable Temperature Coefficients Allows for the precise manipulation of the temperature compensation levels for improved results at various temperatures.

• Multiple Cell Constants Allows use of additional electrodes for best results – usually low or

high ranges.

What is Dissolved Oxygen?Dissolved Oxygen (DO) is a measure of the amount of dissolved gaseous oxygen in a solution. Some gases, such as ammonia, carbon dioxide and hydrogen chloride, react chemically with water to form new compounds. However, gases such as nitrogen and oxygen merely dissolve in water without chemically reacting with it, and exist as microscopic bubbles between water molecules.

There are two main ways in which dissolved oxygen occurs naturally in water: From the surrounding atmosphere, where oxygen in the surrounding air dissolves readily when mixed into water, up to saturation, during water movements; Via photosynthesis when oxygen is produced by aquatic plants and algae as a by-product of photosynthesis. The amount of oxygen dissolved in water is usually measured in percent saturation, or expressed as a concentration in milligrams per litre water. Accurate measurement of dissolved oxygen is essential in processes where oxygen content affects reaction rates, process efficiency or environmental conditions, such as biological wastewater treatment, wine production, bio-reactions, environmental water testing.

Basic Principle in DO MeasurementIn theory, the amount of DO in a solution is dependent on three factors, namely temperature, salinity and atmospheric pressure.

1. Water Temperature Solubility of oxygen reduces as temperature increases. Hence, the colder

the water, the more dissolved oxygen it contains. Since temperature affects both the solubility and diffusion rate of oxygen, temperature compensation is necessary for any standardized DO measurements.

2. Salinity The amount of dissolved oxygen increases as salinity level decreases.

In other words, freshwater holds more oxygen than saltwater. Since the presence of dissolved salts limits the amount of oxygen that can dissolve in water, the relationship between the partial pressure and concentration of oxygen varies with the salinity of the sample.

3. Atmospheric Pressure There is a direct proportional relationship between the solubility of

dissolved oxygen and the surrounding atmospheric pressure. As pressure decreases with increase in altitude, the amount of dissolved oxygen found in water reduces.

To ensure that your dissolved oxygen is not affected by atmospheric pressure, most instruments include barometric pressure compensation. Advanced meters include a built in barometer that measures and adjusts automatically. However, basic meters will make adjustments only after the user inputs the appropriate pressure manually. Atmospheric pressure correction charts included in with certain instrument manuals are also a helpful reference.

DO Electrodes

The measurement of DO requires a special DO electrode that is made up of an anode, a cathode, electrolyte solution and a gas permeable membrane. The material of the membrane is specially selected to permit oxygen to pass through. Oxygen is consumed by the cathode which will create a partial pressure across the membrane. Oxygen then diffuses into the electrolyte solution. In short, a DO meter actually measures the pressure caused by movements of oxygen molecules in water or any other medium. The higher the partial pressure of the oxygen in solution, the higher the oxygen concentration. Currently, galvanic and polarographic electrodes are the predominant methods for measuring dissolved oxygen.

The Galvanic Cell consists of two metals, the positive anode and the negative cathode, connected by a salt bridge between the individual half-cells. As the metal electrodes leave electrons behind as they dissolve in the electrolyte. The different properties of the two metals causes them to dissolve at different rates, hence a potential is created when the number of electrons in either side of the cell differs. The potential is translated into an electric current proportion to the oxygen concentration in the electrolyte if an electrical circuit is created between the two electrodes. The galvanic electrode does not need polarising time and is able to assume operation immediately.

During this process, ions of the more active anode are transferred through the electrolyte to the less active cathode, and deposited there as a plating. In this way the anode is corroded. When the anode material eventually corrodes away, the potential drops and the current halts.

The Polarographic Cell consists of two electrodes placed in the electrolyte: One with fixed potential called the reference electrode, and the other with a variable potential called the polarizable electrode. As voltage is applied to the polarizable electrode, a redox reaction occurs, where electrons break away from the electrode to bond with oxygen in the electrolyte. The rate at which the electrons break away from the polarizable electrode is linearly proportionate to the amount of oxygen available in the electrolyte, hence this movement of electrons is representative of the amount of dissolved oxygen left in the electrolyte.

The advantage of a polarographic cell is that the cathode remains intact. The current flow of the polarographic cell is also linearly proportional to the amount of oxygen present in the electrolyte, enabling the cell to provide highly accurate measurements at low oxygen levels.

BOD & CODThe BOD test measures the molecular oxygen utilized in the biodegradation of organic material and the oxidation of inorganic material. By measuring the amount of oxygen dissolved in samples at the beginning and end of a specified incubation period, the relative oxygen requirements of wastewaters, effluents, and polluted waters can be determined.

BODt (mg/L) = D1 - D2 P

BODt = Oxygen uptake during incubation period t

D1 = DO of diluted sample immediately after preparation (mg/L)

D2 = DO of diluted sample after incubation period t (mg/L)

P = Decimal volumetric fraction of sample used

BOD is similar to the Chemical Oxygen Demand (COD), which also measures relative oxygen-depletion. However, the possible presence of non-biologically oxidizable may render the COD test to be less accurate.

The COD test is often used to measure the amount of organic compounds in water by measuring the amount of oxygen required to oxidize and break down an organic compound into carbon dioxide, ammonia and water. The basis of the COD test is to determine what can be oxidized into carbon dioxide using a strong oxidizing agent in acidic environments. A blank sample, created by adding all reagents to distilled water is usually used as a control in COD measurements.

Both the BOD and COD tests are means to measure the relative oxygen-depletion effect of a waste contaminant, and are widely used to monitor pollution levels. The BOD test measures the oxygen demand of biodegradable pollutants whereas the COD test measures the oxygen demand of biogradable pollutants plus the oxygen demand of non-biodegradable oxidizable pollutants.

COD measures everything that can be chemically oxidized and not just the level of biologically active matter that BOD measures. This is especially important to keep in mind when understanding and comparing COD and BOD results that may contain non-biological oxidizable components.
