摘要：

A liquid chromatography/electrospray ionization tandem mass spectrometry method is described for the determination of aflatoxins B-1, B-2, G(1) and G(2). Samples of naturally contaminated airborne dust and spiked urine were cleaned up on immunoaffinity columns and analysed by liquid chromatography using either mass spectrometry detection or post-column derivatization with bromine and fluorescence detection. With tandem mass spectrometry, detection limits (S/N = 3) calculated as amount ejected on column were: aflatoxin B-1 4 pg, B-2 4 pg, G(1) 5 pg, and G(2) 10 pg.
