Research Abstract

The basic concept and framework of threshold-energy dissociation mass spectrometry have been applied to various tandem mass spectrometers including quadrupole-type instruments. Analysis of fragmentation behavior of some organic molecules and threshold-energies allowed us to establish the basis for the exploitation of the method for identification of small molecules including isomers. An integrated analytical strategy including threshold dissociation and ion mobility tandem mass spectrometry was shown to be promising for characterization of isomeric ions and fragmentation networks.
