浩瀚色谱（山东）应用技术开发有限公司采用SUMMA罐采集空气样品,在预浓缩系统中经3级冷阱捕集后,用气相色谱-质谱联用技术测定环境空气中7种痕量有机硫化物。对试验条件进行优化,使得硫化氢，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种有机硫化物在21.47μg/m3~336.43μg/m3范围内线性良好。试验表明,7种有机硫化物的方法检出限为0.004μg/m3~0.036μg/m3;标准气体平行测定6次结果的RSD为2.7%~6.2%,加标回收率为92.2%~97.5%。用该方法测定实际空气样品,并与傅立叶红外光谱法测定的结果进行比对,结果令人满意。

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.
