Paper Abstract

The experimental set-up using a cw 13C16O2-laser for the real time multicomponent PA gas analysis is described. An intracavity PA-cell combining the `H-' and `T-'geometries simultaneously is used. The applying of a computer for laser lines tuning and a Fourier transform technique for signal processing permits us to obtain the minimum detectable absorption of 1 X 10-9 cm-1 with a time resolution of 30 seconds per one line. The concentrations of gas mixture component are determined by solving the linear equation systems with using a least-squares technique. The results of the experiments on detecting H2O, CO2, NO2, NH3, HNO3, OCS and C2H4 in urban air are reported.
