Gas concentrations are measured using mid-infrared optical absorption spectroscopy.
The light sources are quantum cascade lasers, which are operated to produce wavelength sweeps that cover the absorption lines of the gases. The lasers are mounted in the Analysis Unit and light is directed into the sample cell, where it is partially absorbed by the flow of gas moving through the heated tube.
The remaining light is detected by a receiver and determined using a comprehensive spectral fitting routine.
