Determination of Flumioxazin Residue in Ginger by GC-MS

Abstract

Abstract: Flumioxazin was extracted from sample with acetonitrile and the extract was cleaned up by using SupelcleanTMENVITM- Carb SPE Tube (0.5g, 6ml). The final extract was injected into GC, followed by MS detection under EI ionization and selective ion monitoring mode. The detection limit was 0.006mg/kg. Precision and recovery tests were made at the spike level of 0.02, 0.04, 0.05, 0.1, 0.2mg/kg, and the results were as follows: recoveries in the range of 62%～105%, relative standard deviation 5.2%～18%.

Key words: solid phase extraction, gas chromatography-mass spectrometry(GC-MS), selected-ion monitoring, flumioxazin, ginger
