Abstract: Much progress has been made in pesticide analysis in the past decade. During this time, hyphenated techniques involving highly efficient separation with sensitive mass spectrometric detection have become the methods of choice. Even with such powerful instrumental techniques, a demanding task in pesticide residue analysis is the development of multiresidue methods for the determination of pesticides in air, water, soil, sediment, biota, and food. This chapter summarizes the analytical characteristics of the different methods of sample preparation for the determination of pesticide residues in a variety of food matrices, and surveys their recent applications in combination with gas chromatography, liquid chromatography, and capillary electrophoresis. Techniques such as sonication-assisted extraction, supercritical fluid extraction, microwave-assisted extraction, pressurized liquid extraction, and matrix solid-phase dispersion are covered; applications of these techniques are increasing in the field. Classic as well as promising novel extraction/cleanup techniques, such as solid-phase microextraction, liquid-phase microextraction, molecularly imprinted polymer extraction, stir bar sorptive extraction, and others are also outlined. The advantages and disadvantages of the different methods and instrumental aspects are discussed, and some perspectives for the future are summarized
