Fourier-transform ion cyclotron resonance mass spectrometry is a type of mass analyzer (or mass spectrometer) for determining the mass-to-charge ratio (m/z).
Fourier-transform ion cyclotron resonance mass spectrometry is a type of mass analyzer (or mass spectrometer) for determining the mass-to-charge ratio (m/z) of ions based on the cyclotron frequency of the ions in a fixed magnetic field. The ions are trapped in a Penning trap (a magnetic field with electric trapping plates), where they are excited (at their resonant cyclotron frequencies) to a larger cyclotron radius by an oscillating electric field orthogonal to the magnetic field
An ion cyclotron resonance (ICR) absorption spectrum has been obtained by exciting an ICR spectral segment with . The fundamental principles of Fourier transform mass spectrometry (FTMS) are presented.
An ion cyclotron resonance (ICR) absorption spectrum has been obtained by exciting an ICR spectral segment with a fixed-frequency electric field pulse, followed by broad-band detection, digitization of the (time-domain) transient response, and digital Fourier transformation to produce the (frequency-domain) absorption spectrum. The motion of ions in a FTMS analyzer can be understood in terms of the magnetic and electric fields present in the FTMS analyzer cell.
FT-ICR MS achieves the highest resolution and best mass measurement accuracy of any mass spectrometry method.
The relation of FT-ICR MS to other types of Fourier transform spectroscopy and to the Paul (quadrupole) ion trap is described.

Comprehensive chapters cover the history of ICR and other techniques based on the cyclotron principles of mass analysis and offer a descriptive explanation of the theory involved in fourier transform detection and analysis. Application chapters cover one technique in detail and illustrate its particular area of analysis.

Since its inception in 1974, Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) has proven itself to be a valuable tool for the characterization of biomolecules. FT-ICR MS offers several tandem mass spectrometric techniques which have been utilized for the characterization of lectins with ESI FT-ICR MS, including infrared multiphoton dissociation (IRMPD), electron capture dissociation (ECD), and electron detachment dissociation (EDD).
