The various special features of data treatment are shown on the example of some mixtures measurements by opto-acoustic (OA) carbon-dioxide laser gasometric system. Mathematical methods of OA-signals processing are presented. Application of these methods permit not only quantitatively estimate the components of the gas mixture, but also determine their concentration. The method of qualitative estimation is based on the use of the theory of checking of statistical hypotheses. The mathematical methods for the inverse problem solution is used for the quantitative analysis of gas mixtures. The measurements are performed with carbon-dioxide laser OA spectrometer.
