Title:
PHOTO-DISSOCIATION OF PROTEINS AND PEPTIDES IN A MASS SPECTROMETER
Document Type and Number:
WIPO Patent Application WO/2013/005061
Kind Code:
A3
Abstract:
A method of mass spectrometry is disclosed comprising directing first photons from a laser onto ions located within a 2D or linear ion guide or ion trap. The frequency of the first photons is scanned and first photons and/or second photons emitted by the ions are detected. The ions are then mass analysed using a Time of Flight mass analyser.
