| 摘 要： | 建立柑橘中常见的50种农药残留的气相色谱-质谱(GC-MS)检测方法。样品用乙腈快速提取、无水硫酸镁与氯化钠盐析后,经N-丙基乙二胺(PSA)填料净化,用GC-MS分析。采用选择离子监测模式(selected ionmonitoring,SIM),以保留时间和特征离子定性、峰面积定量。方法的检出限(RSN=3)为0.0038～0.066mg/kg,50种农残的平均收率72.0%～118.2%,相对标准偏差1.7%～19.7%。

| Abstract: | An analytical method for the rapid determination of 50 pesticides residues in citrus by gas chromatography-mass spectrometry(GC-MS) with QuEChERS was established in a selected ion-monitoring(SIM) mode.The pesticide residues in samples were extracted into acetonitrile and salted out by anhydrous MgSO4 and NaCl.Then,the pesticide residues in the supernatant after clean-up on N-propyl ethylenediamine(PSA) cartridge were subjected to GC-MS analysis.Under the optimal conditions,the limits of detection(RSN = 3) o... |
