为满足饮用水源地监测要求,采用吹扫捕集-气相色谱/质谱法同时测定饮用水源地水中乙醛、环氧氯丙烷、丙烯醛、苯系物等27种挥发性有机物.实验中运用程序升温,在26 min内完成检测,采用全扫描(SCAN)方式扫描,提高了化合物的定性能力.方法检出限均低于我国饮用水源地标准限值,回收率为75.6%～111.0%.

In order to meet the monitoring requirements for drinking water sources, purge-and-trap gas chromatography-mass spectrometry (P&T-GC-MS) was used to simultaneously determine 27 kinds of volatile organic compounds (VOCs), such as acetaldehyde, epichlorohydrin, acrolein, benzene series etc. The programmed temperature was used to shorten the running time to 26 minutes for one measurement. Full-scan mode was used to increase the ability for qualitative analysis of VOCs. The detection limits was less than the standard limits for drinking water sources in China and the recovery was 75.6%～111.0%.
