Haohan Chromatographic (Shandong) Application Technology Development Co., Ltd. used cold trap preconcentration gas chromatography/mass spectrometry to determine six kinds of sulfide in the ambient air, including hydrogen sulfide, methyl mercaptan, methyl sulfide, carbon disulfide, dimethyl disulfide and thiophene. The influence of the material of the sampling container was discussed. The linearity of the method is good, and the detection limit of six sulfides is 1.0 μ g/m3～5.0 μ G/m3, the RSD of parallel determination of mixed standard gas is ≤ 8.1%, and the recovery rate is 93.5% ～ 97.3%.
