A study of the suitability of gas chromatography-electron capture detection for the analysis of deoxynivalenol in cereals.

A gas chromatographic-electron capture detection (GC-ECD) method for the analysis of deoxynivalenol (DON) in cereals was investigated. The sample was extracted with a mixture of acetonitrile-water and purified with a MycoSep #225 column. The silylation was performed with Tri-Sil-TBT reagent, followed by dilution with hexane and a washing step with buffer.
