Photoacoustic investigation for atmospheric gas testing

Abstract
In the paper thc possibility of photoacoustic phenomena application for the testing of atmospheric gasses was presented. There were presented some aspects of theoretical analysis of photoacoustic effect as well as the method of the gas concentration determination in complex mixture of various gasses based on spectroscopic investigations. The results of testing measurements obtained by means of photoacoustic experimental set-up elaborated in Institute of Physics at Silesian University of Technology are presented, too.
