ResumoPost-column in-line photochemical derivatization permits fluorescence detection of all four common aflatoxins B1, B2, G1 and G2. Chromatographic evidence indicates that the photolysis causes the hydration of the non-fluorescent B1 and G1 components to the B2a and G2a components respectively. Analysis of naturally contaminated corn samples show no interfering peaks and permits the determination of 1 and 0.25 ppb (w/w) of B1 and B2, respectively.
