چکیده انگلیسی
The method of simultaneous measurement on gas concentration and particle mass concentration by tunable diode laser absorption spectroscopy is developed. The method is validated using a 1.58 μm diode laser with wavelength modulation spectroscopy. The experimental environment of particulated gas flow is imitated by adding uniform-sized quart sands into CO2 gas. Calibrated second harmonic signals are proved to be independent of particle effects but only depend on gas concentration, and particle mass concentration can be calculated from the attenuation of laser power. This technique would be helpful to improve the quality and applicability of tunable diode laser absorption spectroscopy in emission monitoring.
