使用吹扫捕集和M ars-6100气相色谱-离子阱串联质谱联用仪对水中的挥发性有机物进行同时测定。建立了一种同时检测饮用水中26种挥发性有机物的方法，该方法的最低检出限为0.0013μg/L ，精密度（RSD ）在1.1％～12.3％之间，回收率在87％～114％之间。实验结果显示该方法具有灵敏度高、定性和定量准确等特点。%The methed for determination of 26 volatile organic compounds in drinking water was estab-lished using purge and trap system connected with gas chromatography and mass spectrometry. The lowest limits of detection were 0.0013μg/L ,the precision were between 1.1% and 12.3% and recovery was 87%-114% . The results show the method is high sensitive、accurate for qualitative and quatitaive.
