Abstract
A liquid chromatography/electrospray ionization tandem mass spectromet ry method is described for the determination of aflatoxins B-1, B-2, G (1) and G(2). Samples of naturally contaminated airborne dust and spik ed urine were cleaned up on immunoaffinity columns and analysed by liq uid chromatography using either mass spectrometry detection or post-co lumn derivatization with bromine and fluorescence detection. With tand em 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.
