Abstract
In one aspect, an electron-ion reaction module, e.g., an electron capture dissociation module, for use in a mass spectrometer is disclosed, which comprises a chamber, an electron source for generating electrons and introducing the electrons into the chamber, a gate electrode positioned relative to the electron source and the chamber, and a DC voltage source operatively coupled to the gate electrode for applying control voltages to the gate electrode. The electron-ion interaction module can further include a controller operably coupled to the DC voltage source and configured for adjusting the DC voltage applied to the gate electrode to adjust flow of electrons into the chamber.
