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.
noun, Physics. 1. a mass spectroscope for recording a mass spectrum on a photographic plate. noun 1. a mass spectrometer that produces a photographic record of the mass spectrum
noun, Physics. 1. a device for identifying the kinds of particles present in a given substance: the particles are ionized and beamed through an electromagnetic field and the manner in which they are deflected is indicative of their mass and, thus, their identity. noun 1. an analytical instrument in which ions, produced from a sample, […]
noun, Physics. 1. an instrument used to determine the masses of small, electrically charged particles. mass spectroscope See under spectroscope.
noun, Physics. 1. a spectrum of charged particles, arranged in order of mass or mass-to-charge ratios.
