长春市大气气相有机污染物探查

Probe of Organic Vapor Pollutants in the Atmosphere of Changchun City

采用石英毛细管气相色谱及石英毛细管气相色谱-质谱,结合低温吸附,冷凝浓缩等技术,对长春市大气气相有机污染物进行了定性分析。质谱经计算机检索,鉴定出了十一类110种有机物,色谱测定出了40种烃类的保留指数,绘制了沸点与保留指数的关系曲线。

The present paper contains the qualitative analysis of organic vapor pollutants in the atmosphere of Changchun city, by capillary GC and GC-MS methods combined with concentrating technique of freezing and adsorpting at a low temperature. 111 organic pollutants in 11 categories were identified. The plot of boiling point against retention index was drawn. The qualitative result by GC is identical with one by GC-MS.
