Progress on sample preparation techniques for analysis of pesticide residues in foodstuffs

Abstract

The progress on sample preparation techniques for analysis of the pesticide residues in foodstuffs was reviewed. The applications of the supercritical fluid extraction (SFE), solid-phase microextraction (SPME), microwave aided extraction (MAE) and gel permeation chromatography (GPC) in analysis of pesticide residues in foodstuffs were described. Special attention was given to SFE technique and its hyphenation with gas chromatography (GC), high-performance liquid chromatography (HPLC) and gas chromatography-mass spectrometry (GC-MS). The trends of sample preparation techniques for analysis of pesticide residues in foodstuffs were also discussed.
