Haohan Chromatographic (Shandong) Application Technology Development Co., Ltd. uses a gas sampling bag. After the sample is processed by a three-stage cold trap preconcentrator, the gas chromatography is used to analyze hydrogen sulfide, methyl mercaptan, methyl sulfide and dimethyl disulfide in the air. The experiment shows that the linearity of this method is good, and the detection limit is 3.1 × 10-5 mg/m3 ~1.2 × 10-4mg/m3, the precision is 0.8%~1.3%, and the recovery rate of blank spiking is 84.6%~112.0%. This method is accurate, reliable and suitable for the determination of sulfide.
