Abstract: | Thermospray, plasmaspray and dynamic fast-atom bombardment liquid chromatography—mass spectrometry are compared for the identification of six trichothecenes. Thermospray spectra of the trichothecenes exhibit only a very abundant ammonium adduct ion. Plasmaspray, which provides a more energetic ionization process than thermospray, produces some fragment ions in addition to an abundant ammonium adduct ion. The spectra obtained by dynamic fast-atom bombardment exhibit a protonated molecule, a glycerol adduct ion and numerous fragment ions formed by the losses of functional groups as neutrals in various combinations. Thermospray and plasmaspray are suitable only for monitoring of the trichothecenes, whereas dynamic fast-atom bombardment is suitable for monitoring and for structure characterization. |
