Summary:

An analyzer based on Quantum Cascade Laser (QCL) has been developed for chemical sensing of gaseous nitrogen compounds (NO, NO2, N2O and NH3). The QCL can emit lights in a mid-infrared (Mid-IR) region where these nitrogen compounds have strong absorption. This laser optics configuration can give a super fine resolution of the mid-infrared spectrum. Therefore, utilizing this spectrometer can reduce the interference caused by the spectral overlap of co-existing gases in engine exhaust. The developed analyzer has been evaluated using actual engine exhaust to confirm the influence from coexisting gases and the measurement accuracies and stabilities. Very low detection limit (less than 1 ppm) and quick response time (less than 2 sec) have been achieved even with the newly developed analyzer
