| 摘 要： | 建立高效液相色谱-串联质谱检测蔬菜中苯醚甲环唑残留的分析方法。样品采用乙腈提取，经石墨碳黑-氨基串联固相萃取(GCB/NH2 SPE)柱净化，液相色谱分离多反应监测模式下测定，外标法定量。结果显示：苯醚甲环唑质量浓度在1～500ng/mL范围内线性关系良好。苯醚甲环唑在不同基质中平均回收率为79.3%～108.0%，相对标准偏差为2.7%～8.5%，检出限为0.001mg/kg。该方法灵敏度高，准确度、精密度好，满足样品测定的定性、定量要求。

| Abstract: | A method was established to determine difenoconazole residues in vegetables by high performance liquid chromatography-mass/mass(HPLC-MS/MS).Difenoconazole residues were extracted from vegetables by acetonitrile and cleaned up by carbon/amino solid phase extraction(GCB/NH2-SPE) cartridge.The chromatographic separation was achieved by HPLC and the determination was performed by tandem mass spectrometry in a multiple reaction-monitoring mode.The external standard method was used for the quantification of difen... |
