MODERN SAMPLE PREPARATION TECHNIQUES FOR THE ANALYSIS OF FUSARIUM MYCOTOXINS IN CEREALS

This work decribes the suitability of new clean-up techniques for subs equent determination of B-trichothecenes by GC-ECD and of zearalenone by HPLC-FLD. Using the Mycosep(R) multifunctional clean-up columns for purification of B-trichothecenes the clean-up procedure is reduced to a 1-step extract purification, thus saving much time in comparison wi th classical clean-up methods without sacrificing the purity of the ex tract. This work also shows the good performance of immuno-affinity-ch romatography as a new clean-up technique for the determination of ZON in corn.
