Fourier transform-ion cyclotron resonance-mass spectrometer |
---|
A high-frequency mass spectrometer in which the cyclotron motion of ions, having different mass/charge ratios, in a constant magnetic field, is excited essentially simultaneously and coherently by a pulse of a radio-frequency electric field applied perpendicularly to the magnetic field. The excited cyclotron motion of the ions is subsequently detected on receiver plates as a time domain signal that contains all the cyclotron frequencies excited. Fourier transformation of the time domain signal results in a frequency domain FT-ICR signal which, on the basis of the inverse proportionality between frequency and mass/charge ratio, can be converted to a mass spectrum. See also ion cyclotron resonance (ICR) mass spectrometer. |
