The pesticide residues were extracted with acetonitrile under ultrasonic operation, and the extract was separated and detected with the on-line GPC-GC/MS system. The recoveries of the method ranged from 73.06 to 119.9 with the relative standard deviations (RSD) from 0.88 to 11.02. The limits of detection was 0.0003 ~0.009 mg/kg. The method is simple, rapid and characterized with acceptable sensitivity and reproducibility to meet the requirements for the analysis of multiple pesticide residues in oat flour.
