3 Principle

Based on the principle of Michelson's interference, the interference light passes through the sample cell after the beam splitter meets, and the interference light containing the sample information after passing through the sample Arriving at the detector, and then processing the signal by Fourier transform to obtain an infrared absorption spectrum of transmittance or absorbance with wave number or wavelength Figure, the light intensity is proportional to the concentration of hydrogen sulfide and hydrogen sulfide, and then determined by the calibration data and map of the spectrometer The concentration of hydrogen sulfide and hydrogen sulfide.

4 instruments

Liquid Sulfur Hydrogen Sulfide Analyzer. Intrinsic calibration procedure with hydrogen sulfide and hydrogen sulfide concentration, liquid sulfur sample cell and heater Fourier Transform the infrared spectrometer. The technical parameters of each software and hardware should meet the following requirements. a) Intrinsic calibration procedure for hydrogen sulfide and hydrogen polysulfide concentrations. total hydrogen sulfide concentration ranges from 5 μg/g to 500 μg/g. b) Sample cell. portable analysis room, made of corrosion-resistant and easy-to-clean metal material, equipped with KCl detection lens, heated plate Heat and maintain 135 ° C ~ 145 ° C to ensure that the sulfur sample tested is liquid. c) Sample cell electric preheater. tray heater, can control temperature 135 ° C ~ 150 ° C, temperature control accuracy ± 1 ° C. d) Fourier transform infrared spectrometer. mainly composed of light source chamber, interferometer, sample cell, detector, interface and data processing system, instrument The resolution and stability of the device are in accordance with GB/T 21186. The structure of the instrument is shown in Figure 1. ......
