Abstract
A computer-aided optoacoustic gas analyzer based on a continuous13C16C2 laser for multicomponent pollution of atmospheric air is described. The analyzer has the ability to detect absorption of radiation by detected substances at the level of ∼1·10−9 cm−1 at a time resolution of 30 sec. Results of an experiment on simultaneous detection of H2O, CO2, NO2, NH3, HNO3, OCS, and C2H4 in the atmospheric air using 40 laser lines are presented.
