Abstract

The invention provides a carbon monosulfide absorption crosssection measurement device and method. The measurement device comprises a nitrogen protection box, a nitrogen storage tank, a carbon disulfide storage tank, an excitation source, a sample tank, an ultraviolet emission device, a spectrograph and a data acquisition and processing device. Nitrogen is introduced into the sample tank for nitrogen cleaning and introduced into a nitrogen protection chamber for nitrogen protection, influence of air and other experiment pollution gas on an experiment is avoided, carbon monosulfide is chemically separated and obtained on basis of carbon disulfide, characteristic absorption spectra of absorbed ultraviolet light are obtained through a spectrometer, carbon monosulfide absorption cross sectionis obtained according to the characteristic absorption spectra, and carbon monosulfide absorption cross section measurement is realized.

Description

technical field [0001] The invention relates to the technical field of gas detection, in particular to a carbon monosulfide absorption cross section measuring device and method. Background technique [0002] CS is generally formed in plasmas containing sulfur and carbon sources or decomposition products such as sulfur-carbon compounds. For example, already in CH 3 CS was observed in SCN discharges, and CH was reported 3 CS in the SCN discharge may lead to the formation of C and S atoms in the plasma. Plasmas with sulfur-containing precursors can deposit n-type semiconductor chemical vapor deposition (CVD) diamond films by incorporating S into the film structure. Such discharges have been observed to generate CS and CS in the gas phase reaction 2 , and speculate that CS is the substance responsible for incorporating sulfur into the lattice CS also plays a role in atmospheric reactions, such as the production of atmospheric carbonyl sulfide (OCS), which is responsible for ...
