GB/T 14678-1993 Air quality-Determination of hydrogen sulfide, methyl mercaptan, methyl sulfide and dimethyl disulfide-Gas chromatography Details:

Name: Special column for sulfide

Stationary Phase: Dedicated

Specifications: 3m*3mm

Model: HH-sulfide-III

Application: Determination of 9 kinds of sulfides such as hydrogen sulfide, carbonyl sulfide, carbon disulfide, thiophene, methyl sulfide, methyl mercaptan, ethyl mercaptan, ethyl sulfide, dimethyl sulfide, etc.



This standard applies to the simultaneous determination of hydrogen sulfide, methyl mercaptan, methyl sulfide and dimethyl disulfide in odor pollution source exhaust gas and ambient air.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses Summa tank sampling, cold trap pre-concentration to process samples, and gas chromatography-mass spectrometry for the determination of methyl mercaptan, ethyl mercaptan, methyl sulfide, ethyl sulfide, methyl ethyl sulfide in ambient air 7 kinds of odorous sulfides such as sulfide, dimethyl disulfide and carbon disulfide. The results show that the linearity of the method is good, the detection limits of seven sulfides are 8.0×10-4~1.4×10-3 mg/m3, and the RSD range of the mixed standard gas is 3.32%~6.17%. The recoveries ranged from 100% to 117%. The method is accurate and reliable for the determination of malodorous sulfides in ambient air, and can be used for the analysis and detection of malodorous sulfides in conventional ambient air.
