　　Haohan Chromatography uses "adsorption tube sampling thermal desorption gas chromatography-mass spectrometry" to simultaneously determine 5 organic sulfides in ambient air, including methyl mercaptan, ethyl mercaptan, methyl sulfide, ethyl sulfide, and dimethyl disulfide. Under the condition of sample refrigeration, the mass concentrations of the 5 organic sulfides show a good linear relationship with peak area within the range of 5.35 × 10-3 to 8.56 × 10-2, 6.93 × 10-3 to 1.11 × 10-1, 6.93 × 10-3 to 1.11 × 10-1, 1.01 × 10-2 to 1.61 × 10-1 mg/m3, respectively; When the sampling volume is 10 L, the detection limit of the method is 1.13 × 10-3~2.80 × 10-3 mg/m3, the relative standard deviation is 2.76%~7.73%, and the spiked recovery rate is 78.5%~106.0%. There is no significant difference between the actual sample measurement results and the GB/T 14678-1993 method

　　This method is applicable for the simultaneous determination of hydrogen sulfide, methyl mercaptan, methyl sulfide, and dimethyl disulfide in the exhaust of odor pollution sources and ambient air. The detection limit of the flame photometric detector (GC-FPD) of the gas chromatograph for the four components is 0.2 × 10-3~1.0 × 10-3g. When the concentration of the four components in the gas sample is higher than 1.0mg/m3, 1-2mL of gas sample can be directly injected into the gas chromatograph for analysis. Concentrate 1L of gas sample, and the detection limits for the four components are. 2 × 10-3~1.0 × 10-3mg/m3, respectively.
