FIELD: measurement equipment. ^ SUBSTANCE: inventions refer to laser spectroscopy and spectral analysis, and can be used for simultaneous diagnostics of absolute and relative content of carbon oxides CO and CO2 in gaseous medium. For simultaneous content analysis of CO and CO2 molecules there used are CO and CO2 absorption lines entering the spectral range overlapped with frequency-controlled semiconducting laser, and CO absorption lines from fundamental vibration-rotation band 1-0 or obertone of that fundamental absorption band 2-0 or obertone of that fundamental absorption band 3-0, which do not overlap with absorption lines of water vapours and are located near 4.7 mcm, 2.35 mcm, 1.57 mcm correspondingly, and CO2 absorption lines of bands 20001-01101 or 00021-01101, or 30012-00001, which are located in the same spectral ranges and overlapping with the appropriate CO absorption bands. ^ EFFECT: invention allows simultaneous determination of CO and CO2 molecules concentration in gaseous medium. ^ 4 cl, 3 dwg |
