Title: Florisil Solid-Phase Extraction Cartridges for Cleanup of Organochlorine Pesticide Residues in Foods
Abstract: 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.
