A low temperature vacuum cell 220 cm long with windows of quartz, ZnSe, and KBr has been developed for work with the Bruker IFS 125-M high resolution Fourier spectrometer providing a threshold sensitivity to absorption on the order of 10-7 cm-1. The cell allows recording the absorption spectra of gases in the temperature range from 200 to 296 K with the accuracy of 0.9 K in the region 1000–20000 cm-1.
