苏码罐采样预浓缩-GC-MS测定空气中的挥发性有机化合物

Determination of Volatile Organic Compounds in Ambient Air Using SUMMA Canisters with Subsequent Analysis by GC-MS

采用苏码罐采样技术,预浓缩系统与GC-MS联用,优化了系统的测试条件,建立了测定环境空气中41种挥发性物的监测方法。用于环境空气和室内空气的监测,结果令人满意。

Pre-concentrated system combined GC-MS was evaluated for determination of 41 kinds of trace volatile organic compounds in ambient air using SUMMA canister for sampling. The experimental conditions were optimized. This method has been used for the determination of volatile organic compounds（VOCs） in the environmental air and indoor air. The results were satisfactory.
