Recently, the analysis of pesticides residues in many types of foods have become more important because of the increasing demand from EPA regulatory agencies.

The GPC (Gel Permeation Chromatography) clean-up method is widely used to remove lipids, polymers, pigments and other high molecular weight compounds from a wide range of sample matrices including food, tissues, grains, plants and environmental samples. Using this method combined with GC/MS, GC or HPLC, it is possible to detect many pesticides residues with good reproducibility in a relatively short period of time.

Dichloromethane has been used as an eluent for GPC clean-up, but as it may itself cause environmental pollution. To overcome this, the possibility of using a non-halogenated solvent such as ethyl acetate/cyclohexane as eluent was tested recently, but compared with dichloromethane the separation efficiency was inferior.
