ABSTRACT
A capillary supercritical fluid chromatography/mass spectrometry interface incorporating a heated frit restrictor is described. The trichothecene mycotoxins T-2 toxin, deoxynivalenol and roridin A were used to evaluate the effect of restrictor temperature and carbon dioxide mobile phase on the negative ion chemical ionization (CI) spectra of these compounds under electron capture, proton abstraction and chloride attachment conditions. Restrictor temperatures less than 100 degrees C above the melting point of the samples retarded sample transfer into the mass spectrometer, but neither restrictor temperature nor carbon dioxide mobile phase significantly affected negative ion CI conditions.
