Preferred Label : Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometer;
IUPAC acronym : FT-ICR; FT-MS; ICR;
IUPAC definition : 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 or a radio-frequency electric field applied perpendicular
to the magnetic field. The excited cyclotron motion of the ions is subsequently detected
on so-called receiver plates as a time domain signal that contains all the cyclotron
frequencies that have been excited. Fourier transformation of the time domain signal
results in the frequency domain FT-ICR signal which, on the basis of the inverse proportionality
between frequency and the mass/charge ratio, can be converted into a mass spectrum.
The term is sometimes contracted to Fourier transform mass spectrometer (FT-MS).;
