Title:
PHOTO-DISSOCIATION OF PROTEINS AND PEPTIDES IN A MASS SPECTROMETER
Document Type and Number:
WIPO Patent Application WO/2013/005060
Kind Code:
A3
Abstract:
A method of mass spectrometry is disclosed comprising automatically and repeatedly performing multiple cycles of operation, wherein a cycle of operation comprises the steps of: (i) mass analysing first ions; (ii) exposing the first ions to a first photo-dissociation device to form a plurality of second ions and mass analysing the second ions; and (iii) exposing the first ions to a first photo-dissociation device to form a plurality of second ions, fragmenting the second ions to form a plurality of third ions and mass analysing the third ions.
