Abstract
Apparatus and methods are provided that enable the interaction of low energy electrons and positrons with sample ions to facilitate electron capture dissociation (EGO) and positron capture dissociation (PGO), respectively, within multipole ion guide structures. The apparatus and methods described herein allow EGO (and PCO) to be performed within multipole ion guides, either alone, or in combination with conventional ion fragmentation methods.
