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. After t… WebCompared to TOF and Orbitrap, FT‐ICR‐MS had a slower start in metabolomics. FT‐ICR‐MS is an equip-ment with one of the highest resolution power and sensitivity.
