ABSTRACT:
The present invention relates to mass spectrometers capable of performing electron (or positron) capture dissociation, methods of performing tandem mass spectrometry, methods of performing electron capture dissociation, and methods of performing positron capture dissociation. In one embodiment, a mass spectrometer capable of performing electron or positron capture dissociation is provided that comprises a first mass analyzer, a magnetic trap downstream of the first mass analyzer, a second mass analyzer downstream of the magnetic trap, and an electron or positron source positioned such that electrons or positrons may be supplied to the magnetic trap.
