Abstract

A method and apparatus for radial activation of transmission-mode electron transfer ion/ion reactions using a dipolar AC field applied transverse to a transit direction is disclosed. Increases in fragment ion yields and structural information from electron transfer dissociation (ETD) were observed. The method may be used for transmission mode ETD for relatively low charge states of peptides and proteins.
