Gas Analysis Sample Conditioning Components and Systems

Buhler’s components for sample conditioning systems provide advanced technology and expert design in ensuring the most reliable and accurate systems and products on the market today.

A compromise in the design or selection of analytical equipment often leads to errors in measurement, reliability and increased maintenance costs. Our wide range of sampling products ensure a representative sample is presented to the analyzer.

The Buhler analytical solution ensures precise measurement, highly accurate results and an extremely reliable solution for your gas sampling needs.

Sample Probes

Elegantly simple in concept and design, we customize

to meet the needs of any gas sampling application. Our

unique design has a “tool free„ easy filter replacement

feature. Detailed attention is required in the selection of:

• material composition

• heated / non heated

• up or downstream filters

• filters with blowback capacity

• explosion proof version according to ATEX and CSA

Sample Pumps

Sample gas must be transported through the entire

sampling and conditioning system at a steady pressure

and flow. Too high of pressure in a pump can alter the

sample’s chemistry and variable pressure can induce

error in the measurement. Buhler’s unique bellows

pump design ensures steady even pressure and flow

regardless of filter loading. Completely inert wetted

materials, heated and un-heated designs combined

with ease of maintenance make the Buhler pump the

best analytical pump solution. Features include:

• no interference by gas containing condensate

• highly corrosion resistant materials

• ATEX Zone 1 and Class I Div. 1 and 2 available

Sample Coolers

Dry basis or standard condition measurements require

a stable dew point. An unstable dew point will bias the

measurement and in most cases will increase both

analyzer and system maintenance. Buhler Sample Gas

Coolers provide the most stable dew point in the industry

and feature the following:

• fast and efficient dew point stabilization

• single or multistream

• integrated automatic condensate drains

or peristaltic pumps available

• selection of heat exchanger materials

• explosion proof version according to ATEX available

• self controlling, with alarm outputs

Sample Filters

All Buhler sample filters are of analytical grade. The housings

provide easy access for maintenance. Main features include:

• easy to integrate and install

• no threads between head and bowl

• range of elements from fine to coalescing

• appropriate selection of materials

• bypass and drain connections optional

• heated versions available

Moisture Detectors

An essential safety device for your analyzer, the moisture

detectors protect the expensive and sometimes difficult to

replace analyzer components from liquid water.

• easy to install

• adjustable sensitivity:

detects before reaching liquid phase

• filter integrated and stand alone models

Condensate Removal

Any time water dew points are reduced with a

cooler, condensate needs to be removed from the

sample gas stream. Selection of all materials used for

condensate removal is crucial. Condensate removal

technologies include:

• automatic drain for pressurized systems

• integrated or stand alone peristaltic pump

Flow Meters and Accessories

Inert and highly corrosion resistant flowmeters,

regulating valves, shut off and selection valves are

required components of any sampling system. These

components control the flow rate of the sample gas

to the analyzer. Features include:

• highly resistant materials

• suitable for gas or liquid

• bi-stable set point controller (optional)

• easy change of glass or flow indicator while

staying online

NOx - Converter

This unit allows for the accurate and reliable conversion

of NO2 to NO which is a necessary function for NDIR,

NDUV and chemiluminescent NOx analyzers.

• high conversion rates up to 752 °F

• withstands high NO2 concentration

• high exchange capacity

• easy change of reactor cartridge without tools

• highest conversion efficiency over time in the field

• optional NH3 scrubber available

Pre-Engineered Sample Conditioning

Solutions

The SCS series combines all elements

of a sample conditioning system into

pre-engineered off the shelf packages

that can be used for many of the routine

applications. Key benefits of the SCS are:

• no repetitive system engineering

costs

• easy to maintain

• field replaceable as a complete

assembly

• easily customized to meet a variety

of applications

• off the shelf design permits

quick delivery

Analyzers

Buhler’s 40-years of experience in

the gas analysis field enables us

to provide our customers with a

comprehensive range of gas

analyzers. The product range

includes maintenance friendly in-situ

analyzers with laser technology as

well as ZrO2 cells.

For extractive applications single

or multi-channel analyzers can be

equipped with various measuring

cells. Hence, a paramagnetic dumb

bell cell, a ZrO2 module, IR-banks

as well as eletro-chemical cells can

be integrated into our analyzers in

accordance with the application.

The life and accuracy of process analyzers

depends on reliable sample conditioning systems.

These systems must be professionally designed

and the components employed in the systems

should be specifically built for demanding

applications.

Most of the problems that plant managers and

maintenance personnel report are caused by

design faults and the use of unsuitable material

that fail under harsh conditions.

Buhler has supplied sample conditioning systems

to the world market for over 40 years.

DA 00 0001 01/2010

Our markets include chemical plants, power plants

(both nuclear and combustion) petrochemicals,

food industry, automotive and many others.

Buhler’s success and growth in this highly

competitive market depends on one credo

“DO NOT COMPROMISE„.

We continuously improve our range of products

specifically designed for sample conditioning

systems to exceed customer expectations!
