Simultaneous determination of ten anticoagulant rodenticides in tissues by column-switching UHPLC-ESI-MS/MS

Popis výsledku v původním jazyce

This paper describes the development of a method for the simultaneous determination of ten anticoagulant rodenticides (coumafuryl, warfarin, pindone, coumatetralyl, coumachlor, difenacoum, bromadiolone, brodifacoum, chlorophacinone and flocoumafen) in the liver and kidney based on column-switching liquid chromatography coupled with heated electrospray ionization tandem mass spectrometry. The simple sample preparation includes extraction with methanol. A C-18 trapping column was used for online solid-phase extraction before analytical separation with the mobile phase comprising a mixture of 0.1 % formic acid in water, methanol and acetonitrile. Chromatographic separation was achieved using a Thermo Hypersil ultra high-performance liquid chromatography (UHPLC) C-18 column with the mobile phase consisting of 5 mM ammonium formate buffer (pH = 9) and methanol. The column-switching procedure ensured no matrix effects during electrospray ionization (ESI). Extraction recoveries ranged between
