吹扫捕集-气相色谱-氢火焰离子化/电子捕获检测器法在线监测水中19种可挥发性有机物

Online Monitoring of 19 Volatile Organic Compounds in Water by Purge and Trap-gas Chromatography Hydrogen-flame Ionization Detector/Electron Capture Detector Method

基于吹扫捕集技术,本研究自主设计了一套吹扫捕集-气相色谱-氢火焰离子化检测器/电子捕获检测器(P&C-GC-FID/ECD)分析系统,在单台仪器上监测19种水中可挥发性有机物。综合测试结果表明,该系统具备良好的性能,并且主要技术自主国产可控,能满足水中VOCs的监测需求。

Based on purge and capture technology,a set of purge and capture-gas chromatographyhydrogen flame ionization detector/electron capture detector(P&C-GC-FID/ECD)analysis system was independently developed to monitor 19 volatile organic compounds in water.The comprehensive test results indicate that the system has good performance and the main technology is domestically produced and controllable,which can meet the need of monitoring VOCs in water.
