CO2 laser photoacoustic spectrometry - Sensitivity and drift analysis
Original language description
We reported trace gas measurements performed by the eddy correlation technique and we determined the time domain stability criterion for laminar and turbulent flows measured in the street canyon model. The preliminary evaluation of the instrument performance was utilized by in situ measurements of CH3OH light pollutant concentrations. Further, the instrument has been adapted to in situ measurements of C2H5OH trace gas concentrations. We have determined optimal averaging times for C2H5OH measured by CO2laser PAS at static operation connected to wind tunnel. The Allan and Hadamard variance methods were used for stability analysis. Dependence of both values of Allan and Hadamard variances on different degrees of flow turbulence was evaluated for the sample pollutant C2H5OH. The approach used in the study of the influence of turbulence on the optimal averaging time for minimum detectable concentrations has been described. Several measurement series were made to determine the optimum integ
