title: Gel permeation system for removal of fats during analysis of foods for residues of pesticides and herbicides.
abstract: A gel permeation chromatography system has been developed for the rapid cleanup of fatty foods in the analysis for pesticide residues. The narrow elution bands of fats and pesticides coupled with the ease of evaporating the eluting solvent makes this system efficient because of the savings in time and solvents. This system allows a wide range of compounds including organochlorine pesticides, organophosphorus pesticides, industrial chemicals, herbicides, carbamates, and drugs to elute in the cleaned-up fraction.
