摘要

建立了一种μ-QuEChERS结合气相色谱-三重四极杆串联质谱仪(gas chromatography-triple quadrupole tandem mass spectrometry,GC-MS/MS)在10 min内测定桃胶中106种农药残留的方法。样品经μ-QuEChERS方法提取、净化,经超高惰性气相色谱柱(highly inert gas chromatographic column,HIGC)分离,以三重四极杆-串联质谱仪检测分析,基质标准曲线外标法定量。106种农药在0.002 00~0.400 mg/kg范围,其线性相关系数R均大于0.995,对于0.500 g样品的106种农药的检出限为(5.84×10-6)~(2.81×10-3) mg/kg,定量限为(1.95×10-5)~(9.36×10-3) mg/kg,且低、中、高3个浓度添加水平的回收率为72％~109％,相对标准偏差(relative standard deviations,RSDs)为0.73％~10％。该方法具有快捷、污染小、可靠性强的特点,适用于桃胶中多种农药残留的快速定性和定量检测。

Abstract

To establish a method for the rapid determination of 106 kinds of pesticide residues simuletaneously in Peach gum by gas chromatography- triple quadrupole tandem mass spectrometry(GC-MS/MS) with μ-QuEChERS in 10 minutes.The samples were extracted and purified by μ-QuEChERS method, and then the pesticide residues separated by highly inert gas chromatographic column and analyzed by GC-MS/MS.Within the range of 0.002-0.400 mg/kg, the correlation coefficient of all pesticides is higher than 0.995.The detection limit and quantitation were (5.84×10-6)-(2.81×10-4) mg/kg and (1.95×10-5)-(9.36×10-3) mg/kg, respectively.Overall recoveries and relative standard deviations (RSDs) were ranged from 72% to 109% and from 0.73% to 10%, respectively.The method has the advantages of fast, less pollution and better reliability, which is suitable for rapid qualitative and quantitative detection of multiple pesticide residues in peach gum.

Key words： μ-QuEChERS; highly inert gas chromatographic column; gas chromatography-triple quadrupole tandem mass spectrometry; peach gum; pesticide residues
