Gas-liquid chromatographic and gas-liquid chromatographic-mass spectrometric determination of fenvalerate and permethrin residues in grasshoppers and duck tissue samples.
A procedure is described for determining fenvalerate and permethrin residues in grasshoppers and duck tissues. Samples are Soxhlet-extracted with hexane and cleaned up by gel permeation chromatography with an in-line alumina column. Samples are analyzed by gas-liquid chromatography with electron capture detection, and confirmed by gas-liquid chromatography-mass spectrometry. The average recovery from fortified tissues was 97%.
