摘　　要：采用预冷冻浓缩系统和气相色谱-质谱联用,建立了测定空气中39种挥发性有机物的分析方法,该法用苏玛罐或Tedlar气袋采集空气样品经-160℃液氮预冷冻浓缩后,用GC-MS检测。该方法采样简便,灵敏度、准确度高,已应用于室内空气和环境空气的测定,取得满意的结果。Cryo-concentration combined GC/MS was evaluated for determination of 39 kinds of trace volatile organic compounds（VOCs） in air, This method is simple, precise, and sensitive, It has applied to determination of VOCs in analyzing the indoor air and environmental air sample. And satisfactory results were obtained.
