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!
