根据吸附剂对挥发性有机物（VOCs）的吸附原理，结合吹扫捕集仪自行研制了 VOCs气体采样管，利用 VOCs 气体采样管结合吹扫捕集仪与气相色谱仪联用，建立了完整的大气中 VOCs的分析方法，并应用于空气中挥发性卤代烃（VHCs）的检测。结果表明，VOCs 气体采样管对 VHCs 具有很好的吸附解吸效率，分析方法检出限为0.02～0.1μg/m3（进样量1L），RSD 在3.7％～8.7％之间，回收率92.4％～98.2％，满足痕量物质分析要求。

Based on the principles of Volatile Organic Compounds (VOCs)adsorption on various sorbents,an air sample tube matching up to the Purge and Trap Concentrator for VOCs was developed.Cou-pled with Purge and Trap Concentrator and gas chromatography (GC),a comprehensive method to determi-nate the VOCs in ambient air was established.The results of all experiments indicated that the method was a-vailable for trace organic matter analysis,the method detection limits (MDL)of this method is up to 0.02 -0.1μg/m3 (when the sample volume is 1L)and average recoveries for the target analytes were in the range of 92.4% -98.2%.The method also showed good linearity (R2 >0.99)and precision (<9%)values.
