A method of rapid analysis for residual pesticides in agricultural products with the gel permeation chromatography-two dimensional gas chromatography and mass spectrometer (GPC-GC-GC-MS) is proved.The method is simple for preparation sample; it only needs one step of extraction preparation process of first step for many common preparations.GPC-GC-GC-MS (shimadzu): Shim-pack VP-ODS 4.6mm×l50mm gel column (shimadzu); GC-GC column: DB-5MS 15m×0.25mm (i.d.)×0.1μm; DB-17MS 30m×0.25 mm (i.d.) ×0.25μm (Agilent); the programmed temperature vaporization injector.
