| 摘 要： | 毛细管色谱-质谱法测定了环境大气中挥发性污染物。用液氧冷冻法和常温吸附法(TenaxGC)分别采集大气样品,然后用两种系统进行浓缩,并进入毛细管色谱-质谱体系,完成了有机污染物的定性定量分析。解决了一些色谱-质谱联用中的问题。并且还讨论了无分流进样问题,比较了两种采样方法。用此方法测定了某炼油厂环境大气中的污染物。

| Abstract: | The determination of volatile pollutants in ambient air was carried out by GC/MS. Airsamples were collected by the liquid oxygen cryogenic method and the porous polymer(TenaxGC) absorbent method. transferred to a sample concentrating loop, and injected into capillarycolumn GC/MS. Both qualitative and quantitative analysis of organic matters have been achi-eved with this measuring system. Some questions in GC/MS System were solved. These methodswere applied to the measurement of atmospheric organic pollutants in certain oil refinery. |
