IUPAC. Analytical Division. Compendium of Analytical Nomenclature (the Orange Book). Definitive Rules, 1979 (see also Orange Book 2023) |
| Double-focusing mass spectrometer |
|---|
|
An instrument that uses both direction and velocity focusing so that an ion beam initially diverging and containing ions of different energies is separated into beams according to the mass/charge ratio. The ion beam is measured electrically. |
