The automated system for laser optoacoustic analysis of the atmospheric air controlled by the “Iskra-226” computer has been developed. The system sensitivity is 1.10^-7 cm^-1 The system enables: to record the absorption spectra of substances on the CO₂-laser lines; to carry out the primary processing of the spectral data; to identify the multicomponent gas mixtures from their spectra using the target transformation; to calculate the number of components; to detect the substance expected to be present in the mixture; to isolate the spectra of components absent in the data base from the mixture spectrum.
