Abstract
The present invention relates to a new method for fragmenting ions in a mass spectrometer through the use of electron transfer dissociation, and for performing sequence analysis of peptides and proteins by mass spectrometry. In the case of peptides, the invention promotes fragmentation along the peptide backbone and makes it possible to deduce the amino acid sequence of the sample, including modified amino acid residues, through the use of an RF field device.
