Determination of underivatized aflatoxins B2, B1, G2, and G1 in ground hazelnuts

The combination of immunoaffinity SPE purification and enrichment with FLD detection without derivatization offers a sensitive analytical method for the quantification of the aflatoxins G2, G1, B2, and B1 in ground hazelnuts.
The Vanquish Fluorescence Detector provides sufficient trace level detection performance down to 1 μg/kg for aflatoxins B1 and G1 and 0.1 μg/kg for B2 and G2, enabling aflatoxin analysis in ground hazelnuts far below the tolerance levels defined by the European Commission.
