ion cyclotron resonance mass spectrometer

A device for storing and analysing ions, which are held in a metal cell/chamber by a static magnetic field and a coincident electrical field generated by potentials applied to the walls of the cell. Ions attain a coherent cyclotron orbit with a frequency proportional to mass, and are detected by monitoring the alternating electrical current generated in detector plates by their regular orbits. A Fourier transform converts the monitored frequency to ion mass.
