Abstract

A system and method for mass analysis of an ion beam. The system includes a mass selector, at least one multipole ion guide, and a mass analyzer. In the system and method, precursor ions are selected with a desired mass to charge ratio. Electrons are injected into the multipole ion guide. The precursor ions are fragmented into product ions via electron capture dissociation from the injected electrons. The product ions are passed to a mass analyzer for a mass analysis.
