mass spectrograph

A device that uses electrical or magnetic fields to determine the masses of atoms or molecules in a sample. A beam of ions is passed through the electrical or magnetic field. The field deflects the ions at different angles depending on their masses, thereby breaking the beam into separate, identifiable bands.
