Signal’s Infrared analysers offer superior performance in a wide variety of applications for the monitoring of all absorbing gases.
The principle that gases and liquids absorb light is something that we are all aware of without probably ever thinking much about it. Looking at the absorbtion of characteristic wavelengths of light to determine the concentration is the most widely used analytic technique for gases.
There are various designs of IR detector from very simple to very complicated, the most popular including dual beam and gas filter correlation both of which types refer to techniques used to reduce cross interference.
Non Dispersive Infrared (NDIR) Multi-gas analysers are available in 1, 2, 3, 4 or 5 gas channel configurations, offering high levels of performance and flexibility. Options include CO, CO2, CH4, NO, N2O, SO2, HCl and O2.

The Flame Ionisation Detection (FID) method was first developed in the 1950s for the laboratory analysis of organic chemicals. Later, when environmental regulations began to limit the emissions of volatile organic chemicals (VOCs) in the 1970’s and 1980’s, the FID method was adapted for emissions monitoring. Signal Group was one
In a significant advancement for emissions monitoring technology, Signal Group is proud to announce that our 3010 MiniFID has achieved certification from the National Institute of Environmental Research (NIER) under Notification No. 2023-70. This certification marks a pivotal development in our commitment to providing cutting-edge technology that meets rigorous global
As the world urgently seeks ways to decarbonise, James Clements from Signal Group explains how gas analysis will perform a vital role – not just for CO2 but for all of the important greenhouse gases. The climate crisis is forcing nations to urgently find ways to lower their greenhouse gas
