气相色谱-串联质谱法快速检测玉米粉中乙草胺、异丙甲草胺和三唑酮残留OA北大核心CSCDCSTPCD
Simultaneous determination of acetochlor, metolachlor and triadimefon residue in corn flour by gas chromatography-tandem mass spectrometry
建立了玉米粉中乙草胺、异丙甲草胺和三唑酮残留检测的气相色谱-串联质谱(GC-MS/MS)分析方法。样品采用乙腈浸提3 h、过两次0.22μm尼龙66微孔过滤膜后，以气相色谱-串联质谱 EI离子源，多反应监测模式(MRM)检测。结果表明：在0.005～1 mg/L范围内，3种供试农药的质量浓度与其相应的峰面积间呈良好的线性关系，决定系数(R2)均大于0.999。在0.025、0.050和0.25 mg/kg 3个添加水平下，3种农药的平均回收率为9…查看全部>>
A gas chromatography-tandem mass spectrometry (GC-MS/MS) method was established for the simultaneous determination of acetochlor, metolachlor and triadimefon residue in corn flour. The samples were extracted with acetonitrile for 3 h, and the upper acetonitrile layer was filtered with 0.22 μm nylon membrane.The samples were then determined by GC-MS/MS. The results showed that the calibration curve was linear in the range of 0.005-1.0 mg/L. The determin…查看全部>>
