Determination of T-2 and HT-2 toxins in oats and oat-based breakfast cereals by liquid-chromatography tandem mass spectrometry

Abstract

This protocol specifies an accurate and sensitive method for the determination of T-2 and HT-2 toxins content in oats and oat-based foods using liquid chromatography with tandem mass spectrometry detection. T-2 and HT-2 toxins are extracted from the test material with a mixture of acetonitrile and water. The filtered extract is dried, reconstituted with a mixture of methanol and water, then purified on a polymeric solid-phase extraction cartridge. Toxins are finally eluted from the column with methanol and quantified by reversed phase high performance liquid chromatography with tandem mass spectrometry detection.
