摘要
微捕集技术可作为连接样品与GCMS之间的桥梁,使分析过程实现了样品的采样-浓缩-进样分析在线操作,具有操作简单、快速、无需溶剂,回收率高,样品预处理时间短,分析运行成本低等特点,可用于大气样品中痕量有机污染物的全自动分析。
Microtrap technique can connect the sample and GCMS,which accomplished on-line sampling-pretreatment-analysis.The trace VOCs,MT-GCMS method shortened the pretreatment time,and reduced the operation expenses and the analytical expenses.Therefore,it was a small,simple,effective adsorption and desorption technique which eliminated the need for solvent and complicated apparatus,despite of its low price.The analysis of trace VOCs in ambient air can be automatic by MT-GCMS.
