苏码罐采样气相色谱-质谱法测定环境空气中挥发性有机物方法探讨

Explore Ways about Determination of Volatile Organic Compounds in Ambient Air using SUMMA Canisters with Subsequent Analysis by GC-MS

文章利用苏码罐采样气相色谱-质谱法测定环境空气中39种挥发性有机物,该方法在采样过程中不存在吸附剂可能穿透的问题,前处理过程不需使用大量的解析溶剂,且检出限低,灵敏度高,所测有机污染物种类多,并可重复进样。适用于韶关市环境空气中VOCs的监测。

Pre-concentrated system combined GC-MS was evaluated for determination of 39 kinds of trace volatile organic compounds （VOCs） in ambient air using SUMMA canister for sampling. The method without the problem for may penetrate the adsorbent m the sampling process, pretreatment process without the use of large amounts of solvent, and low detection limit, high sensitivity, the many kinds of organic pollutants, and the repeated sampling. Monitoring for VOCs in air environment in Shaoguan city.
