目的: 采用超高液相色谱串联质谱法对猪肉中9 种兽药残留进行测定。方法: 经前处理后的样品，通过多反应监测模式检测，按照1.0、5.0、10.0 μk/kg 浓度加标空白猪肉样品，重复考察回收率、RSD。结果: 加标浓度1.0μk/kg 时，平均回收率和RSD 分别为43.42% ～ 79.61、2.87% ～ 18.45%；加标浓度5.0μk/kg 时，平均回收率和RSD 分别为58.78% ～ 95.36%、2.93% ～ 7.25%；加标浓度10.0μk/kg 时，平均回收率和RSD 分别为59.51% ～ 96.44、1.84% ～ 8.51。结论:该方法前处理简便、通量大，且具备较好的重现性、准确度，适用于多种兽药残留的同时测定。“,”Objective: To determine 9 veterinary drug residues in pork by ultrahigh liquid chromatography-tandem massrnspectrometry. Method: The samples after pretreatment were tested in the multi-reaction monitoring mode, and the blank pork samplesrnwere spiked at the concentration of 1.0, 5.0, and 10.0 μk/kg, and the recovery rate and RSD were repeated. Results: When the spikedrnconcentration was 1.0μk/kg, the average recovery and RSD were 43.42%~79.61 and 2.87%~18.45%, respectively; when the spikedrnconcentration was 5.0μk/kg, the average recovery and RSD were 58.78%~95.36%, respectively. , 2.93%~7.25%; when the spikedrnconcentration is 10.0μk/kg, the average recovery and RSD are 59.51%~96.44, 1.84%~8.51, respectively. Conclusion: The method hasrnsimple pretreatment, high throughput, good reproducibility and accuracy, and is suitable for the simultaneous determination of multiplernveterinary drug residues.
