环境空气中VOC_S在线监测法与SUMMA罐采样气相色谱-质谱法比对研究

Research of the Comparison of Continuous Emission Monitoring Method and SUMMA Canister Sampling & GC-MS Analyzing Method of VOC_S

定性比较了环境空气VOCS在线监测法和SUMMA罐采样GC-MS法的基本原理、检测化合物种类和适用范围,并对标样实验、日均浓度、小时浓度从统计学角度进行了定量比对。研究表明,VOCS在线监测法监测结果与实验室方法有较好可比性,可用于相关领域VOCS的连续监控。

This paper firstly compared the basic principle, detected compounds and application scope of the continuous monitoring method and SUMMA Canister/GC-MS method of VOCs. The standard sample experiment was made and the daily average and hourly average concentration of VOCs were also compared by statistic analysis. It＇ s deduced that the continuous monitoring instruments could be applied for continuous monitoring in related fields based on the reasonable consistency between the two methods.
