Determination of the total number of u00econs in a espectrometro cyclotron resonance mass of u00econ using resonance of magnetron of u00econ

摘要

Invention patent: b "determination of the total number of u00econs in a espectrometro cyclotron resonance mass of u00econ using resonance of magnetron of u00econ" d .The total number of ions created or obtained during an ionization event or the introduction of ions in a mass spectrometer for ion cyclotron resonance Fourier transform is determinedBoth using an experimental technique in MRI as an experimental technique out of resonance. Both techniques exploit the movement of magnetron ion.In the technique in MRI spectrometer is excited in the mode of magnetron and the only sign of resonance resulting from this excitation is detected to determine the total number of ions.In the technique outside of the resonance mode of the magnetron is excited to a frequ00b3u00eancia which is next to frequ00b3u00eancia of magnetron while detecting simultaneously the movement of ions resulting from it.The technique outside of the resonance leaves the population of ions in a state that is sensitive to subsequ00b3entes analyses.
