mass spectrometer

A device used to measure the masses and relative concentrations of atoms and molecules. It utilizes the Lorentz force generated by external magnetic field on a moving charged particle, in which the particles are deflected by the magnetic field according to their masses. Once deflected, the particles are detected and recorded electrically to provide a mass spectrum of the input beam of ions.
