Abstract Analysis of underivatized trichothecenes using oxygen negative chemical ionization (ONCI) Gas Chromatography/Mass Spectrometry (GC/MS) with a Townsend Discharge source is described. The spectra of nine trichothecenes obtained using this method of ionization are shown. Analysis of several types of agricultural samples were carried out to demonstrate the capabilities of ONCI–GCMS as a screening method for trichothecenes.
