Abstract

In this paper, various designs of non-resonant photoacoustic cells with a different arrangement of microphones are investigated. It is demonstrated that it is possible to expand the dynamic range of measurement of gas concentration using the special configuration of cell cavities and the specific location of the microphone. The suppression of resonant acoustic effects occurring in the measuring photoacoustic cell is characteristic of this cell cavity design. Given this suppression, only the primary sound wave affects the microphone diaphragm. The implementation of a new cell design allows us to extend the range of measurement of SF6 gas impurity concentration in the atmosphere from 100 - 1000 ppm up to 10 - 10,000 ppm.
