A method for the determination of deoxynivalenol (DON) in cereals has been developed and tested. The method is based on solid phase extraction in a column and subsequent separation by HPLC-MS. DON was detected with a MS detector in positive mode. The method is inexpensive, fast and highly sensitive. The method was used for the determination of deoxynivalenol in barley and malt, with the detection limit 25-30 μg kg-1. Changes in the DON content after malting were followed using the method.
