Chemiluminescence
Signal offer chemiluminescence reference method analysers to suit any budget.
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 manufacture a range of analysers for NOx using chemiluminescence, heated, vaccum and ambient according to performance requirement and budget constraints.
S4 QUASAR
Chemiluminescent Detector (CLD) NOX analysers for NO/NO2/NOx measurement in engine emissions, combustion studies, process plant, Emission monitoring and medical gas production.
Managing NOx gas emissions from combustion
Pollution can only be managed effectively if it is monitored effectively. So, as political pressure increases on measures to limit the emissions of the oxides
Simple and accurate gas calibrator
Signal Group’s highly accurate but simple to operate Gas Divider, the 821S is designed for testing the linearity and calibration of almost any gas analyser.
Transportable VOC emissions analyser submitted for QAL1 certification
