| DRAFT DEFINITION |
| Double-focusing mass spectrometer |
|---|
| A mass spectrometer that uses a magnetic sector for m/z focusing and an electric sector for energy focusing of an ion beam. |
| Considered between 2004 and 2006 but not included in the 2006 PAC submission |

IUPAC. Analytical Division. Compendium of Analytical Nomenclature (the Orange Book). Definitive Rules, 1979. |
| 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. |
