使用高分辨飞行时间质谱(Q-Tof)和沃特世(Waters)UNIFI筛查平台完成某流域受污染水体样中未知药物和个人护理品(PPCP)的筛查分析,并使用高灵敏度三重四极杆质谱对结果进行确证.10份未知样品经高分辨质谱和UNIFI筛查平台分析,共检出4—20种残留物,浓度均在μg·L-1级.结果经三重四极杆质谱确证,两套方法结果一致.高分辨质谱与串联四极杆质谱相结合可快速准确地解决应急突发事件.
Screening analyzes of unknown drugs and personal care products (PPCP) in contaminated water samples from a river basin were performed using the Q-Tof and Waters UNIFI screening platforms and high sensitivity Triple quadrupole mass spectrometry to confirm the results.The 10 unknown samples were analyzed by high resolution mass spectrometry and UNIFI screening platform, a total of 4-20 kinds of residues were detected at the concentration of μg · L-1, Confirmation by pole mass spectrometry, the results of the two methods are consistent, and the combination of high resolution mass spectrometry and tandem quadrupole mass spectrometry can quickly and accurately resolve emergencies.
