Low-Temperature Cell for Studying Absorption Spectra of Greenhouse Gases
- 7 Downloads
A low temperature vacuum cell 220 cm in length with windows of quartz, ZnSe, and KBr has been designed for working with the high resolution Bruker IFS 125-M Fourier spectrometer. It provides a threshold sensitivity to absorption on the order of 10–7 cm–1, and allows recording absorption spectra of gases in the temperature range from 200 to 296 K in the region 1000–20 000 cm–1 with an accuracy of 0.9 K.
