LC-MS/MS同时检测烟草中的6种杀菌剂OA北大核心CSTPCD
Simultaneous Determination of 6 Antiseptics in Tobacco with LC-MS/MS Method
为测定烟草中的杀菌剂残留量,利用液相色谱-串联质谱(LC-MS/MS)建立了一种同时检测烟草中6种杀菌剂的方法:烟草样品提取液经处理后,在Atiantis dC18柱上以乙腈-水(含0.1％甲酸)为流动相进行分离,用LC-MS/MS在多反应监测(MRM)模式下测定,内标法定量.采用该方法测定了145个国内外烟草样品中6种杀菌剂农药的残留量.结果表明:①6种杀菌剂线性范围是5～200 ng/mL,线性关系良好(R2＞0.999),平均回收率为85.…查看全部>>
A method basing on high performance liquid chromatography-tandem mass spectrometry (LC-MS/ MS) was developed for determining the antiseptic residues in tobacco. The analytes extracted from tobacco samples were separated on C18 column (150 mm×2.1 mm×3 μm) using acetonitrile-water (containing 0.1% formic acid) as mobile phase. The antiseptics were determined by a tandem mass spectrometer with internal standard under multiple reaction monitoring (MRM)mode. The …查看全部>>
