采用溶剂萃取、GPC净化和GC/MS-SIM联用技术，建立了农产品中95种农药残留的快速检测方法。例如，甲苯、二氯甲烷、乙酸乙酯、四氢呋喃和环己烷。3）GC/MS-SIM对95种农药的检出限满足实际应用要求。该方法对5种农产品中的86种农药进行了回收率测定，结果满意，可用于农产品中多种农药残留的快速检测。
A method for rapid determination of 95 kinds of pesticide residues in agricultural products by solvent extraction, GPC clean-up and GC/MS-SIM was developed.1) A mixed solvent of acetone-ethyl acetate-n-hexane (2:9:9) was selected for extraction, with anhydrous sodium sulfate as a drying agent.2) GPC elution profiles of pesticides and major components in agricultural products were studied with various organic solvents, i. e., toluene, dichloromethane, ethyl acetate, tetrahydrofuran and cyclohexane. Toluene was selected as the most suitable mobile phase for GPC with well-swollen Bio Beads S-X3.3) Detection limits of 95 pesticides by GC/MS-SIM were sufficient for practical use. Eighty-six pesticides spiked into 5 kinds of agricultural products gave good recoveries by the proposed method, which is considered to be satisfactory for the rapid determination of multiple pesticide residues in agricultural products.
