浩瀚色譜（山東）應用技術開發有限公司采用SUMMA罐采集空氣樣品,在預濃縮系統中經3級冷阱捕集后,用氣相色譜-質譜聯用技術測定環境空氣中7種痕量有機硫化物。對試驗條件進行優化,使得硫化氫，羰基硫，甲硫醇、乙硫醇、甲硫醚、二硫化碳、噻吩、乙硫醚和二甲二硫醚等9種有機硫化物在21.47μg/m3~336.43μg/m3范圍內線性良好。試驗表明,7種有機硫化物的方法檢出限為0.004μg/m3~0.036μg/m3;標準氣體平行測定6次結果的RSD為2.7%~6.2%,加標回收率為92.2%~97.5%。用該方法測定實際空氣樣品,并與傅立葉紅外光譜法測定的結果進行比對,結果令人滿意。

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.
