Zusammenfassung:SYSTEMS AND METHODS FOR MEASURING TRACE CONTAMINANTS IN GAS MATRIX USING INTEGRATED CAVITY OUTPUT SPECTROSCOPY A laser absorption spectrometry system for gas measurement is provided. The system includes an integrated cavity output spectroscopy (ICOS) assembly. The assembly includes a gas cell including a cell body defining an optical cavity, one or more tunable diode lasers having one or more nominal wavelengths, and a reflective collimation mirror positioned in an optical path between the one or more tunable diode lasers and the gas cell.
