Signal’s analysers are recognised as the best practical analytical method for NOx detection in a wide variety of applications.
Chemiluminescence is the word given to describe a chemical reaction which produces light. In this instance it is the reaction between nitric oxide, NO and ozone. Each reaction produces a photon of light, therefore from the amount of light produced it is possible to deduce the number of molecules of NO in the reaction chamber, and hence the concentration.
This method is specific to NO and so has no cross sensitivity to other gases that might be present in your sample. CO and H2O can act to absorb the light, a quenching effect, and so a reaction chamber under vacuum can be utilised to reduce this effect where accurate readings are required.
Signal manufactures a range of analysers for NOx using chemiluminescence, heated, vacuum and ambient according to performance requirements and budget constraints.
Chemiluminescent Detector (CLD) NOX analysers for NO/NO2/NOx measurement in engine emissions, combustion studies, process plant, Emission monitoring and medical gas production.

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
