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.
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
The technology development team at Signal Group have announced the launch of yet another market leading innovation for its Series IV gas analysers – a
Continuous Emission Monitoring (CEMs) operators are already familiar with the need to calibrate their stack analysers using certified calibration gases. Frequent calibration against an accurate
