Abstract
The nitrogen components (NO, NO2, N2O and NH3) analyzer has been developed utilizing Quantum Cascade Laser (QCL). The QCL can emit in a mid-infrared region where these nitrogen components have strong absorption. This laser optics configuration can give us 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 gas. The developed analyzer has been evaluated using actual engine exhaust gas to confirm the influence from coexisting gases and the measurement accuracies and stabilities.
