Industrial gas analysis solutions
Biogas plant, wastewater treatment or recycling yard: we measure the gases that decide yield, safety and clean exhaust air – with process measurement technology and sample gas conditioning, as a complete system on request.
Industrial gas analysis measures the composition of process and exhaust gases continuously – for process control, safety and emission monitoring. Fresenius Instruments measures by NDIR, thermal conductivity, paramagnetically and electrochemically, and conditions the sample gas beforehand.

FAQ
Frequently asked questions
What is industrial gas analysis?
The continuous measurement of the composition of process and exhaust gases – for process control, safety and emission monitoring. Measurement is usually extractive: a pump draws the gas through a sampling line to the device.
Which measuring principles does Fresenius Instruments use?
Infrared (NDIR) in the dual-pressure reference method for many IR-active gases, thermal conductivity for hydrogen, paramagnetic oxygen measurement and electrochemical sensors. Which principle fits depends on the gas, the measuring range and the gas matrix.
Why is sample gas conditioning needed?
Humidity and particles distort the measurement. A sample gas cooler dries the gas, filters and condensate traps hold back dust and water – for stable readings.
For which industries are there ready-made solutions?
We show biogas plants, wastewater treatment plants and recycling plants in detail, each with a plant graphic, measuring points and a configurator. We measure gases in many other processes too – talk to us.
How do I find the right solution?
Via the technical information sheet, in a conversation with our team or with Tory, our digital advisor. We design measuring ranges, sampling line and installation together with you.
