HaohanHH一sulfide-III环境空气中有机硫化物测定9种硫化物专用柱

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7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) Application Technology Development Co., Ltd. uses a SUMMA tank to collect air samples, and after being trapped by a 3-stage cold trap in a pre-concentration system, gas chromatography-mass spectrometry is used to determine 7 kinds of trace organic sulfides in ambient air. . The experimental conditions were optimized so that seven organic sulfides, including methyl mercaptan, ethyl mercaptan, methyl sulfide, carbon disulfide, thiophene, ethyl sulfide and dimethyl disulfide, were in the range of 21.47 μg/m3~336.43 μg/m3 Linearity is good. The test showed that the detection limits of the seven organic sulfides were 0.004μg/m3~0.036μg/m3; the RSDs of the six parallel determinations of standard gases were 2.7%~6.2%, and the recovery rates of standard additions were 92.2%~97.5% . The method was used to measure the actual air samples, and the results were compared with those obtained by Fourier transform infrared spectroscopy, and the results were satisfactory.
