ULTRA.sens® UVRAS

ULTRA.sens® UVRAS

For the detection of NO and H2S an EDL (electrodeless gas discharge lamp) is used. A combination of both technologies (UVRAS & UVLEDs) allows simultaneous gas analysis of NO, NO2 and SO2 in the lower ppm range, which is particularly important in flue gas analysis (CEM)2.

In the EDL, N2 and O2 are converted to NO and produce selective UV radiation. With this radiation a cross sensitivity free NO measurement is made possible. This method is called UV resonance spectroscopy (UVRAS).
