ORANGE BOOK DEFINITION

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

Nier-Johnson geometry

An arrangement for a double-focusing mass spectrometer in which a deflection of π/2 radians in a radial electrostatic field analyser is followed by a magnetic deflection of π/3 radians. The electrostatic analyser uses a symmetrical object-image arrangement and the magnetic analyser is used asymmetrically.
