1.0 INTRODUCTION Thank you for your purchase. The Model 8501 Oxygen Permeation Analyzer has been designed to provide accurate and uncomplicated measurements of oxygen transmission rates (OTR) through flat film barriers. The instrument is capable of measuring films with an OTR greater than 1 cc/m

2/day (0.07 cc/100 in

2/day).

We have incorporated into the instrument an electrochemical sensor of our own development and the finest grade electronic components to compliment its performance. This manual is arranged in a manner we feel will provide the greatest ease of reference and use. We are proud of our active program of research and development and wish to know if you encounter any difficulties in your application.

This symbol is known as the ‘Crossed-out Wheelie Bin Symbol’. When this symbol is marked on a product it means that consideration should be given to the disposal of the product, parts or accessories. Only discard electrical/electronic items in separate collection schemes which cater for the recovery and recycling of the materials contained within. Your co-operation is vital to ensure the success of these schemes and for the protection of the environment.

IMPORTANT Please read this manual before attempting to install or operate the equipment. In some variations the sample gas in this equipment is heated to very high temperatures and therefore no combustibles should be present at a limit to cause explosions. The equipment should be electrically connected and grounded in accordance with good standard practice and at the correct voltage. (Refer to the voltage tag label on the back panel.)

No responsibility is accepted by Systech Instruments Limited for accidents resulting from improper use of this equipment.

2.0 PRINCIPLE OF OPERATION The Model 8501 uses our proprietary sensor to detect oxygen transmission rates through flat film barriers. Flat film samples are clamped in a diffusion chamber (Figure 1). Pure oxygen (99.9%) is introduced into the upper half of the sample chamber while an oxygen-free carrier gas, such as nitrogen, flows through the lower half of the chamber. Molecules of oxygen diffuse through the film into the lower chamber and are conveyed to the sensor by the carrier gas. This allows for direct measurement of the oxygen without using complex extrapolations. The oxygen transmission rate of the test film is displayed as either cc/100in

2/day or

cc/m2/day.

3.0 INSTALLATION AND ADJUSTMENT

3.1 Voltage Selector/Fuse Cartridge The power entry module on the back of the instrument serves many purposes. It not only allows attachment of the power cord, but also contains the fuses and allows the supply voltage of the instrument to be selected for either 110/120 VAC or 220/240 VAC operation. Changing the supply voltage requires removal of the cartridge located just below the IEC receptacle for the power cord. To determine the set voltage range for the instrument, view the instrument from the back and note the voltage range that reads upright to the bottom edge of the cartridge. This range is the range to which the instrument is set. The small white arrow beneath the voltage statement should also align with the white arrow that is stamped upon the module body. To change the supply voltage range, remove the power cord (if connected) and insert a small, straight screwdriver into the slot on the top edge of the cartridge. Pry the cartridge away from the instrument until it can be grasped by the fingers and removed completely. Then simply flip the cartridge over and press it back into place to alter the voltage range. Refer to Figure 2 below.

110-120 VAC setting 220-240 VAC setting

Figure 2. Selecting the proper supply voltage. Note that the cartridge also contains two fuses. Both of these fuses must be installed to ensure proper operation of the instrument. The fuses are rated 5A @ 250 V and are a slow-blow type. Replace only with fuses of equivalent ratings.

3.2 Connecting Gas Lines For best results, oxygen-free nitrogen (<5 ppm oxygen) and pure oxygen (99.9% or better) should be used for analysis. These gases should not contain any hydrogen. Use of gases containing hydrogen will result in sensor damage. An oxygen trap should be used to remove traces of oxygen from the nitrogen. Oxygen traps can be purchased through Systech Instruments. NOTE: The inlet pressure of both gases must be set between 1.4 – 1.6 bar, (20 - 23 PSI). If the supply pressure is not within this range, then erroneous measurements will result. A drawing of the back panel is located below (Figure 3). The back panel consists of four brass fittings for gas connections. There are two fittings for both oxygen and nitrogen. These fittings are marked VENTS and INPUTS. Connect the nitrogen to the NITROGEN INPUT and oxygen to the OXYGEN INPUT. The fittings are

1/8 inch Swagelok type compression fittings. Do not over tighten the nuts when connecting the gas lines to the inlet and outlet fittings. The gas vents should be free of restrictions to flow or any source of back pressure.

5.0 SAMPLE PREPARATION AND TESTING A representative sample of film should be selected for analysis. Ideally, this sample should be free of wrinkles, creases, or folds. It is recommended that film sample be handled with care. Handle film samples only by the edges. Fingerprints can alter the transmission rates of some films. A circular template is included with the instrument. Before using the circular template, place the supplied cutting pad on a flat, solid surface. Put the film sample on the cutting pad and hold the template on top of the film sample. Carefully cut around the perimeter of the template using a sharp utility knife. Remove the top portion of the sample chamber by unscrewing the chamber knobs. These knobs are constructed such that they cannot be removed completely from the chamber cover. Apply a small amount of grease to the rim of the lower sample chamber. Spread a thin coat evenly around the edge about ½ inch wide. Do not apply any grease to the upper chamber or the o-ring on the chamber cover. Carefully place the film sample on the sample chamber. Be sure not to get grease on the area of the film being tested. Press the film into the grease to create a tight seal. Pull the film tight to remove any wrinkles. Replace the chamber cover and tighten the chamber knobs.

5.1 Film Testing Connect oxygen-free nitrogen and pure oxygen to the INPUT ports on the back of the instrument as described under Section 3.2, Connecting the Gas Lines.

1. Remove the sample chamber cover by turning the three knobs counter clockwise until they are loose. The knobs are constructed such that they cannot be removed from the chamber cover. Therefore, the knobs only need to be loosened in order for the cover to be removed.

2. Prepare the chamber and sample as described above.

3. Replace the sample chamber cover and tighten the knobs a little at a time until each is

uniformly snug.

4. Check the “tESt” parameter setting before starting the test. Many films reach steady-state levels with “tESt” set to 30 minutes.

5. Regulate the pressure between 1.4 – 1.6 Bar, (20 – 23 psi) to set the flow rate to 35cc/min for

both nitrogen and oxygen. Use an external flow meter to measure the flow rates on the nitrogen and oxygen VENTS on the back of the unit. The flow on the “B” VENT usually will be 5-12 cc/min.

6. Press the green “TEST” button to start the test. The status indicator LED will move from the

“Idle” position to the “Purge” position.

NOTE: The test may be stopped at any time by pressing either the “CAL” button or the “TEST” button.

7. After about 30 minutes, the status light will move from “Purge” to “Test”.

The instrument will stay in “Test” mode for the length of time specified by the “tESt” parameter. After this time has expired, the OTR value will flash on and off. This is the final OTR value for the film being tested. The display will continue flashing until the “Enter” button is pressed

5. Fit the Oxygen Trap bypass pipe to the Oxygen Trap connections on the rear of the instrument.

6. Connect the calibration gas to the NITROGEN INPUT port on the back of the instrument. Regulate the pressure between 1.4 – 1.6 Bar, (20 - 23 psi) to set the flow rate to 35cc/min. Use an external flow meter to measure the flow rate on the VENT of NITROGEN on the back of the unit.

7. Change the “CAL” parameter in the menu to match the certified level of oxygen in your

calibration gas.

8. Place the provided metal plate in the chamber as described under Section 4.2, Sample Preparation

9. Press the blue “CAL” button on the front panel. The status indicator LED will switch from

“Idle” to “Purge”.

10. After about 30 minutes, the “Purge” light will turn off. At this time the oxygen readings in the left window should be stabilizing.

11. Press the “Enter” button after the readings stabilize to calibrate the instrument. The

instrument is now calibrated.

12. Shut off the calibration gas at the cylinder regulator and remove the pipe from the rear of the instrument.

13. Remove the Oxygen Trap bypass pipe and refit the pipes leading to the Oxygen trap, onto the instrument trap connections.

14. Reconnect the Oxygen and Nitrogen supply pipes. NOTE: Ensure these are connected to the correct place as serious damage can be inflicted on the instrument if the Oxygen is connected to the nitrogen input.

15. The instrument should now be ready for use. NOTE: In order to cancel the calibration routine at any time, press either the “CAL” button or the “TEST” button; “ABORT” will appear on the display.

6.2 System Validation / Calibration using Calibration films. Model 8501 is supplied with certified Calibration film (PCF-850101) that could be used for system validation or calibration. To validate the system by using Calibration films follow section 5.1 with test time “tESt” set to 30 min. The system is considered to have passed validation if the measured OTR value is within +/- 5% from the film certified value. Calibration film could also be used to Calibrate the Model 8501 if calibration gas is not available. To calibrate the system by using Calibration set test time “tESt” to 90 min. Follow the below sequence to calibrate your instrument:

1. Place the Calibration film in the chamber as described under Section 4.2, Sample Preparation.

2. Press the green “CAL” button on the front panel. The status indicator LED will switch from

“Idle” to “Purge”.

3. After about 35 minutes, the “Purge” light will turn off and “Test” light will turn on. At this time the OTR readings in the right window should start changing.

4. Wait 50-60 minutes for OTR reading to stabilize and start Illinois Client software.

5. In “Output (to instrument)” window key in “SPAN?1” and push “send”. Read value in “Reply

(from instrument)” window.

6. Calculate the “simulated span” coefficient by dividing certified calibration film OTR value by actual OTR value on display.

7. Calculate a “New SPAN 1” value by multiplying an actual “Span?1” value you have in Illinois

Client by the “simulated span” coefficient.

8. Enter a “New SPAN 1” value in “Output (to instrument)” window in Illinois Client software by keying in “span=1 x.xxx, where x.xxx the “New SPAN 1” value and push “send”, Reply from instrument should be “0”. OTR value on display should change proportionally to the “simulated span” coefficient.

9. Press the “Enter” button to finish the calibration. The instrument is now calibrated.

Example: If your Calibration film has a Certified value of 62.3 cc/m2*day and your actual OTR reading is 65.3 cc/m2*day then your “simulated span” coefficient is 62.3 / 65.3 = 0.95. Read the “span?1” value (usually between 0.02 and 0.04). Lets say it is 0.0312. Multiply 0.0312 by 0.95 (0.0312*0.95 = 0.02964). It will be a “New Span 1” value. Note: Systech Illinois recommends using Gas Calibration to maintain better system accuracy.
