Abstract

The fulfillment of quality and regulation requirements for thermo-chemical industrial processes rely on new measurement technologies based on laser-optical methods. Here we present a robust multi-channel, multi species measurements system for the quantification of exhaust gas species direct at the tail pipe end of a driving car. The application of the TDLAS-spectrometer as well as results of a syn-fuel test drive are presented and discussed in detail regarding optical system robustness and uncertainties.
