| Tóm tắt: | Title screen A diagram is suggested and numerical simulation is carried out of a photoacoustic gas analyzer with a thermal source and first order interference filter for carbon isotope ratio analysis. An optimal spectral range for gas analyzer operation is selected. In the wavelength range selected, the spectral parameters of the atmosphere are analyzed, as well as of some gases, which, being present in samples under study, could affect the measurement results. The gas analyzer suggested allows us to measure the carbon isotope ratio 13C/12C in CO2 samples with a minimal error of about 0.5‰, and could be useful for detection of such gases as SO2, CO, and NH3, absorption lines of which fall in the selected spectral range.
