  • 摘要:New analytical procedure for the determination of fosetyl-aluminium in hop cones (also called “hops”) was developed. Liquid chromatography–atmospheric pressure chemical ionisation tandem mass spectrometry (LC–APCI-MS/MS) allowed a highly selective determination of this fungicide which facilitated the sample preparation. The sufficiently low detection limit (1 mg/kg of dried hops) with the acceptable method performance characteristics (RSD 9%, recovery 76% – at the level of 10 mg/kg) complies with the need to inspect the observance of maximal residual limit 100 mg/kg. The application of LC-MS technique thus provided an effective way of fosetyl-aluminium determination in the complex hops matrix.
