摘要
讨论了空气中挥发性有机化合物 (VOCs)的监测分析方法研究进展。重点介绍了空气中 VOCs的采集、分析和测定 ;简要叙述了样品前处理的新方法——固相微萃取法 (SPME)
Advances in research on the sampling and analytical methods of VOCs in the ambient air are reviewed. VOCs are collected on various adsorbents such as Tenax and activated carbon. The samples are traditionally desorbed using organics solvents(CS\-2) and thermal desorption, but new methods for extracting VOCs in the air is solid phase microextraction(SPME). The analysis of VOCs is usually carried out by gas chromatography\|mass spectrometry(GC\|MS) with electron and negative chemical ionization methods or high\|performance liquid chromatography(HPLC).\;
