title: Florisil solid-phase extraction cartridges for cleanup of organochlorine pesticide residues in foods.
abstract: Florisil solid-phase extraction cartridges were evaluated for cleanup of organochlorine pesticide residues in food extracts. Elution patterns and recoveries were determined for 24 organochlorine pesticides. A range of elution solvents was evaluated. A 2% ethyl ether-petroleum ether eluant optimized overall recoveries while minimizing interferences from coextractants.
