GC/MS Determination of Organic Sulfides in Ambient Air
Determination of organic sulfur compounds in ambient air by GC/MS

Name: Sulfur packed column
Stationary phase: dedicated
Specification: 3m*3mm
Granularity: 60-80 mesh
Material: PTFE
Model: HH-SJSW-III
Application: Malodorous sulfur gas detection, gas chromatography




Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. uses SUMMA tanks to collect air samples, which are trapped by a 3-stage cold trap in the pre-concentration system, and then gas chromatography-mass spectrometry is used to determine 7 trace organic sulfides in ambient air. . The test conditions are optimized so that 9 kinds of organic sulfide, including hydrogen sulfide, carbonyl sulfide, methyl mercaptan, ethyl mercaptan, methyl sulfide, carbon disulfide, thiophene, ethyl sulfide and dimethyl disulfide, are at 21.47μg/m3~ The linearity is good in the range of 336.43μg/m3. Tests have shown that the detection limit of the method for 7 kinds of organic sulfides is 0.004μg/m3~0.036μg/m3; the RSD of the results of 6 parallel determinations of standard gases is 2.7%~6.2%, and the recovery rate of standard addition is 92.2%~97.5% . This method is used to measure actual air samples and compare them with the results measured by Fourier Infrared Spectroscopy. The results are satisfactory.
