Abstract Thermospray ionization with repeller-induced collisionally activated dissociation (repeller-CAD) has been used to acquire mass spectra of a series of dyes. These were obtained by applying a voltage of 400 V on the wire repeller. The mass spectra contained a large number of fragment ions which were useful for structural elucidation. Some of these fragment ions were found to be similar to those obtained by thermospray tandem mass spectrometry with CAD and some of them were similar to those obtained by electron ionization using a particle beam liquid chromatrography/mass spectrometry interface. The results indicate that more than one mechanism is involved in the fragmentation process. (Copyright (c) John Wiley and Sons Limited, 1990.)
