Multi Mycotoxin Analysis in Food Products Using Immunoaffinity Extraction

We developed a method for the simultaneous determination of deoxynivalenol, T-2 toxin, HT-2 toxin and zearalenone in wheat and biscuit by liquid chromatography/electrospray ionization/tandem mass spectrometry coupled with immunoaffinity extraction. This chapter describes a method to extract, clean-up, and quantitate these mycotoxins and the effect of the ion suppression of multifunctional column and IAC in the clean-up were compared.
