Infrared
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.
S4 PULSAR
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.
up to 5 channels
low ranges E.g. 0-10 ppm CO
5 user-configurable ranges + autorange per channel
fast speed of response
New demands for enhanced Greenhouse Gas monitoring
Increasing political action on Climate Change is prompting a new requirement for process operators to improve the accuracy and reliability of greenhouse gas (GHG) emissions
Monitoring solvent emissions to ensure compliance
Governments from around the world have implemented environmental regulations to reduce the emissions of volatile organic compounds (VOCs) from industrial processes. For example, according to
Monitoring NOx in combustion products and processes
In the following article we outline the environmental and health issues associated with NOx, and emphasise the importance of monitoring nitrogen oxides. We also describe
