摘要
采用苏玛罐对密闭空间空气采样,预浓缩仪收集其中的VOCs,通过GC-MS进行累积浓度的分析,建立了一套对密闭空间VOCs进行分析检测的方法,初步摸索了空间VOCs浓度的变化规律,为密闭空间大气质量控制提供了依据。
The air sample was collected by SilcoCan at diferent time in working closed cabin,concentrated through the ENTECH 7100,analysed by GC-MS.This method is simple,precise and sensitive.It can be applied to determination of VOCs in the air in closed cabin.The result is good.
