摘 要：
建立鸡肉中噻节因的超高效液相色谱串联质谱(UPLC-MS/MS)残留测定方法。鸡肉样品选用乙腈提取,采用UPLC-MS/MS多反应模式(MRM)进行分析测定。噻节因添加质量在0.2~10μg范围内,方法平均回收率为87.6%~101.6%,相对标准偏差为2.44%~5.90%。方法的最小检出量为0.005 mg/L,最低检测浓度为0.01 mg/kg。该方法简单、准确,重复性较好,适用于禽蛋中噻节因的残留检测。

摘 要：
A method for determination of dimethipin residues in chicken by ultra-high performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS) was established.The chicken samples were extracted by acetonitrile,then analyzed by UPLC-MS/MS under the multiple reaction monitoring(MRM) mode.The average recoveries ranged from 87.6% to 101.6% with the relative standard deviations(RSD) of 2.44%-5.90% when the fortified concentrations were 0.2-10 μg.The limit of detection was 0.005 mg/L,and the limit of quantification was 0.01 mg/kg.This method was simple,accurate,and was suitable for determination of dimethipin residues in chicken samples.
