Air quality Determination of hydrogen sulfide, methyl mercaptan, methyl sulfide and dimethyl disulfide
Air quality Determination of hydrogen sulfide, methyl mercaptan, methyl sulfide and dimethyl disulfide Details:

Name: Special column for sulfide
Specifications: 3m*1/8
Model: HH-HH-SJSW-III
Application: GB/T 14678-93 Air quality-Determination of hydrogen sulfide, methyl mercaptan, methyl sulfide and dimethyl disulfide-Gas chromatography


Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a method for the simultaneous determination of methyl mercaptan, methyl sulfide and dimethyl disulfide in ambient air by Suma tank sampling, pre-concentration combined with gas chromatography-mass spectrometry, and sample preservation experiments. The results showed that the three odor substances had good linear relationship in the given range, the correlation coefficients were all above 0.995, the detection limit ranged from 0.2 μg/m 3 to 0.3 μg/m 3 , and the recoveries were 84.8% to 97.3%. The standard deviation is 1.2%～5.7%. The method is suitable for the determination of methyl mercaptan, methyl sulfide and dimethyl disulfide in ambient air.
