KTG170 Ultraviolet Analyzer

Basic Principle

The principle of using high-precision absorption spectroscopy technology to measure sulfur gases is based on the Beer-Lambert law. It utilizes the characteristic absorption spectra of gases such as hydrogen sulfide, methanethiol, dimethyl sulfide, and dimethyl disulfide. Differential absorption spectroscopy technology is employed to eliminate interfering components, and then the concentrations of each gas are inversely calculated according to the characteristic differential absorption spectral signals of each component gas.
