摘要
建立了动物源性食品中9种喹诺酮类药物残留量的液相色谱-电喷雾串联四极杆质谱测定方法.样品经阳离子交换固相萃取柱净化后,采用多反应监测(MRM)模式,进行LC-MS/MS分析.方法检出限均为0.05μg/kg,在0.05～50μg/kg添加水平范围内,喹诺酮类药物回收率为65.8%～94.6%,相对标准偏差为5.3%～9.1%.
Using MCX cartridge for extraction and cleanup, a method for the simultaneous analysis of 9 quinolone residues in food samples was developed by ultra performance liquid chromatography-electrospray tandem mass spectrometry. The detection limits were all 0.05μg/kg. The recoveries and relative standard deviations were 65.8%-94.6% and 5.3%-9.1% at 0.05-50μg/kg spiking levels, respectively.
