LENS FOR ELECTRON CAPTURE DISSOCIATION, FOURIER TRANSFORM ION CYCLOTRON RESONANCE MASS SPECTROMETER COMPRISING THE SAME AND METHOD FOR IMPROVING SIGNAL OF FOURIER TRANSFORM ION CYCLOTRON RESONANCE MASS SPECTROMETER

摘要

PURPOSE: lens ECD (dissociation) captures electronics, FT-ICR MS (Fourier transformation) the spectrometer Mass of ion cyclotron resonance has identical, and a kind of signal for improving FT-ICR MS is provided to increase the interaction between probability, electronics and a molecular ion are by the collision area electronics and above-mentioned molecular ion between increasing, to obtain advantage to improve the FT-ICR MS of ECD fragment ion signals. ;CONSTITUTION: lens ECD includes first electrode (211), second electrode (212) and third electrode (213) and the 4th electrode (214). First and second electrode is disposed in separates (D1) by being mutually in a first direction. Third electrode and the 4th electrode are set to by being mutually the second direction separated (D2). The position that first and second electrode is disposed in the magnetic field in space is formed along first direction, to capture electronics. Third electrode and the 4th electrode apply the second direction in magnetic field to trapped electron. First and second electrodes include hole, are respectively formed. ;The 2013 of copyright KIPO submissions
