Abstract:
An electron source for electron-induced dissociation in an RF-free electromagnetostatic cell for use installation in a tandem mass spectrometer is provided. An electromagnetostatic electron-induced dissociation cell may include at least one magnet having an opening disposed therein and having a longitudinal axis extending through the opening, the magnet having magnetic flux lines associated therewith, and an electron emitter having an electron emissive surface comprising a sheet, the emitter disposed about the axis at a location relative to the magnet where the electron emissive surface is substantially perpendicular to the magnetic flux lines at the electron emissive surface.
