Capillary column for analysis of malodorous sulfide in ambient air
Capillary column for analysis of malodorous sulfide in ambient air Details:

Name: Special capillary for sulfide
Model: HH-Sulfur-30
Specification: 30m*0.32mm*0.5um
Application: Determination of ambient air hydrogen sulfide, methyl mercaptan, ethyl mercaptan, methyl sulfide, ethyl sulfide, carbon disulfide, dimethyl disulfide

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses Suma tank sampling, cold trap top concentration processing sample, gas chromatography mass spectrometry combined method to determine methyl mercaptan, ethyl mercaptan, methyl sulfide, ethyl sulfide, methyl ethyl 7 kinds of malodorous sulfides including sulfide, dimethyl disulfide and carbon disulfide. The results show that the method has good linearity, the detection limit of 7 kinds of sulfides is 8.0×10-4～1.4×10-3mg/m3, and the RSD range is 3.32% when the mixed standard gas is measured in parallel. ～6.17%, and the recovery rate of standard addition is 100%～117%. This method is accurate and reliable for the determination of malodorous sulfide in ambient air, and can be used for the analysis and detection of malodorous sulfide in conventional ambient air.
