Solid Phase Microextraction of Organophosphate Insecticides and Analysis by Capillary GC/MS

Courtesy of Sigma-Aldrich Co., LLC

SPME was used to extract an aquatic sample for analysis of organophosphate insecticides by gas chromatography/mass spectrometry (GC/MS).  An SPME fiber coated with 8.5um of polyacryate yielded detection limits ranging from 0.10 to 0.56ug/L. SPME is a quick and highly sensitive sample preparation technique that eliminates the use of solvents.
