Determination of quinolones in aquaculture waters by ultra performance liquid chromatography-tandem mass spectrometry(超高效液相色谱-串联质谱检测养殖水体中喹诺酮类抗生素)
建立了一种通过超高效液相色谱-串联质谱法(UPLC-MS/MS)测定养殖水体中14种喹诺酮类药物的方法.水样经甲酸酸化预处理后,采用HLB固相萃取柱富集并净化目标物,以0.2%体积分数的甲酸水溶液-甲醇为流动相,经过梯度洗脱分离,串联质谱多反应监测模式测定,再由外标法定量.结果显示,14种喹诺酮药物浓度为0.5~50.0 µg • L-1时线性良好,线性相关系数大于0.995.空白水样在5.00,50.0和100 ng • L-1 3种添加水平下的加标回收率为79.8%~95.4%,相对标准偏差均小于10%. 14种喹诺酮药物的检出限为1.00~1.50 ng • L-1,定量限为3.50~5...
