In order to find a suitable mobile phase for gel permeation chromatography (GPC) without using dichloromethane, we have fractionated corn oil, spinach color, paprika color, fluvalinate and chinomethionat by GPC on two columns. The solvent mixtures used in this study were ethyl acetate-cyclohexane (1: 1), ethyl acetate-cyclohexane (3: 7) and acetone-cyclohexane (3: 7). When the pesticide fraction was identified as the possible maximum collection from fluvalinate to chinomethionat, corn oil and paprika color were practically excluded from the pesticide fraction, using a cyclohexane-rich eluent. Spinach color was 71% eliminated from the pesticide fraction with acetone-cyclohexane (3: 7) as the eluent. The results suggest that suitable mixtures for residual pesticide analysis would be acetone-cyclohexane (3: 7) and ethyl acetate-cyclohexane (3: 7), depending upon the column selection.
