SOLID-PHASE EXTRACTION AND GAS-CHROMATOGRAPHIC DETERMINATION OF FLUMETHRIN RESIDUES IN HONEY

A gas chromatographic method to determine flumethrin ('Bayvarol') in honey samples is described. The method consists of solid-phase extraction with RP C-18 cartridges, clean-up if required on silica cartridges, and quantitation of the active ingredient with an electron capture detector using deltamethrin as internal standard. Compared to previous methods it is very rapid, and a number of samples can be prepared simultaneously. The minimum detectable quantity is 0.005 mg kg-1 and mean recoveries are of the order of 95%.
