Abstract
The description of the improvement of the experimental setup based on Fourier spectrometer Bruker IFS-125 and 30-meter multipath optical cell is given in the paper. The improvement includes the cell equipment with a system of automatic adjustment of the number of beam passes without its depressurization and ensures the cell work at high temperatures.
