The method and apparatus of the positron capture dissociation or electron capture dissociation

摘要

In the present invention, a method for performing a viable mass analyzer, the tandem mass spectrometry capture dissociation (or positron) electronic, how to run the electron capture dissociation, and a method to perform a positron capture dissociation. In one embodiment, a viable mass analyzer is provided a positron capture dissociation or electron capture dissociation, and the first mass analyzer, mass analyzer, a magnetic trap on the downstream side of the first mass analyzer I comprises a positron and electron source or sources are arranged with a second mass analyzer downstream of the magnetic trap, electrons or positrons to be supplied to the magnetic trap.
