A gas chromatographic/mass spectrometric assay has been developed for the simultaneous measurement of Z ami~3,gdimethylimiidPzoM5.flquinoxal (MeIQx) and 2-amino-3,4,8-trimetbylimidazo[4,5--]quinoxaline (DiMeIQx) in fried beef. The method employs capillary column gas chromatography, electron capture
