摘要	研制出一种基于吸附管采样/冷阱聚焦方法的环境大气挥发性有机物(Volatile organic compounds,VOCs)富集系统。环境大气中的VOCs先被吸附管采样,之后转移聚焦至冷阱中,冷阱热解析后VOCs随高纯载气进入GC-FID系统中。使用标准气体(苯、甲苯、乙苯)测定系统性能,实验结果表明:本系统设计的冷阱对于VOCs(苯系物)聚焦效率达到90%以上,标准样品相对标准偏差均小于3%,线性相关系数均大于0.99.该系统运行稳定,满足对环境大气的VOCs富集的需求。
其他摘要	An enrichment system for volatile organic compounds(VOCs)in ambient air based on adsorbent tube sampling/cold trap focusing method was developed.The VOCs in ambient air are sampled firstly by the adsorbent tube,and then focused on the cold trap.After the cold trap thermal analysis,the VOCs enter the GC-FID system with the high purity carrier gas.The performance of the system was measured by using standard gases(benzene,methylbenzene,ethylbenzene).The experimental results show that the cold trap designed by this system has a focusing efficiency of more than 90%for VOCs(benzene series),and relative standard deviation of standard samples is less than 3%,and the linear correlation coefficient is greater than0.99.The system is stable in operation,and satisfies the demand for enrichment of VOCs in the ambient air.
