Abstract

A rapid method was developed to determine the residue levels of 46 pesticides in unprocessed hops and hop products (pellets, extract). This method utilizes liquid extraction, solid phase extraction, and finally gas chromatography or liquid chromatography, each combined with tandem mass spectrometry. For hops and hop pellets, a limit of quantification of 0.1 mg/kg or lower could be achieved for all active compounds. The limits of quantification are always a factor of two higher for hop extract.
