采用离子交换固相萃取-超高效液相色谱-串联质谱法同时测定了动物组织中的8类14种非甾体抗炎药(Non-steroidal anti-inflammatory drugs,NSAIDs)残留.动物组织样品经乙腈-乙酸乙酯(1∶1,V/V)提取、乙腈饱和正己烷除脂、Oasis MCX阳离子交换固相萃取柱除杂后,用液相色谱-质谱联用仪电喷雾电离,多反应监测模式检测.本方法的检出限为3.0～10.0μg/kg;,定量限为10.0～25.0 μg/kg;添加浓度在10.0～1000.0 μg/kg范围内,牛肉组织中的回收率为62.9％～108.4％,相对标准偏差小于10％；猪肉组织中的回收率为63.4％～117.0％,相对标准偏差小于9％.
