Analysis of Complex Gas Mixtures
The combination of the IR measurement with the thermal conductivity measurement enables the
complete determination of complex gas mixtures in many cases.
The FTC400 comprises both technolgies, thermal conductivity measurement and infrared mea-
surement in one housing. Thermal conductivity measurement is influenced by a disturbing quan-
tity causing a cross sensitvity measurement. Modeling of the cross sensitivity and additional
measurements with the IR sensor allow the complete determination of complex gas mixtures.
The thermal conductivity measuring method, combined with other gas-analysis methods, pro-
vides the input signals for a computational compensation process which was modeled before-
hand in an experiment. Up to now, systems with several analyzers were to determine the various
input signals. By means of the integrated IR and humidity measurement, as well as the internal
computing capacity, an integrated solution for the determination of homonuclear and noble gases
in complex gas mixtures is achieved.
