title: Characterization of the mycotoxin fumonisin B1: comparison of thermospray, fast-atom bombardment and electrospray mass spectrometry.
abstract: The utility of thermospray mass spectrometry (TSMS), fast-atom bombardment mass spectrometry (FABMS), and electrospray mass spectrometry (ESMS) for the analysis of Fumonisin B1 is investigated. In addition, the analysis of two different standards of Fumonisin B1 as well as an inoculated corn culture extract that contained Fumonisin B1 is reported. The results of these efforts show that ESMS, as well as FABMS and a combination of FAB and tandem mass spectrometry (FABMS/MS), provide useful data for the characterization of Fumonisin B1. The detection limit was 50 pg for Fumonisin B1 when analyzed by full scan FABMS, and 5 pg when analyzed by single-reaction monitoring FABMS/MS.
