| Zusammenfassung | Based on a new Vertical-Cavity Surface-Emitting Laser (VCSEL) we developed a spectrometer for absolute CO determination in high pressure and high temperature environments by means of the Tuneable Diode Laser Absorption Spectroscopy (TDLAS). This laser minimizes strong interferences by CH4, CO2 and H2O possible in combustion processes by accessing the P8 absorption line at 2365 nm in the first rovibrational overtone of CO. With this spectrometer it was possible to measure CO with N2 for pressures up to 0.65 MPa with an excellent detection limit of 540 ppb∙m∙Hz-0,5. |
