| 摘 要： | 目的建立正负离子切换-超高效液相色谱-串联质谱法同时测定鸡肉中43种兽药残留量的分析方法。方法鸡肉样品经甲酸提取液涡旋提取,固相萃取净化, 10 mmol/L甲酸铵稀释, ACQUITY UPLC HSS T3色谱柱(2.1 mm×100 mm, 1.8μm)色谱柱分离,以0.05%甲酸溶液和0.05%乙腈进行梯度洗脱,正离子多反应监测39种兽药,负离子多反应检测4种兽药,外标法定量测定药物的含量。结果 43种兽药定量限为5μg/kg,标准曲线在0.4～100.0 ng/mL范围内均呈良好的线性关系。在空白鸡肉中3个不同添加水平下,平均回收率为60%～120%之间,变异系数为0.7%～12%。结论该方法准确、快速、灵敏、稳定,适合作为鸡肉中43种兽药残留量的测定。
