摘要：Air quality monitoring is a primary activity for industrial and social env ronment. The goverment identifies the plluants that each industry must monitor. Especially,the VOCs(Volatile Organic Compounds),which are very harnful to human body and environment atmosphere,should be contolled under the govemment policy. However,the VOCs. which have not been confimned in emission sources are very difficult to monitor. It is needed to develop the monitoring system that alwl the continwous and in siu measurement of VoCs mixture in different environmental matrices. Gas chromatography and mass spectrometry are the most prevalent current techniques among those available for the analysis of VOCs. Bu,they need a large size analytical instrument,which costs a great deal for purchase and operation. In addition,it has some limitations for real- time environmental monitoring such as location problems and slow processing time. Recently,several companies have commercialized a portable VOCs measurement systems,W hich cannot classify various kinds of VOCs but total quantities. We have developed a VoCs measurement system,which recognizes various kinds and quanities of VOCs, such as benzene,toluene,and xylene (BTX). Also,it can be used as a stand - alone lype and/or fixed lype in the vehicle with rack for real - time environmental monitoring.
