Abstract
A method of photo-fragmentation is provided generating a beam of ions from a sample with an ion source, filtering the beam of ions in a filtering region to select desired ions, and photo-fragmenting the desired ions in a photo-fragmentation region having a higher pressure than the filtering region to generate fragment ions predominantly by prompt fragmentation. An apparatus for photo-fragmentation is provided having an ion source configured to generate a beam of ions from a sample, a filtering region for selecting desired ions, a photo-fragmentation region having a higher pressure than the filtering region to generate predominantly prompt fragmentation of the selected desired ions, an inlet for providing gas to the photo-fragmentation region to maintain a pressure in the photo-fragmentation region that is higher than the pressure in the filtering region, and a photon source emitting a beam of light for photo-fragmenting the selected ions in the photo-fragmentation region.
