Abstract

A high resolution, second-order double-focusing mass spectrometer has been constructed for the precise determination of atomic mass differences. The instrument has a mean radius of curvature in the electrostatic analyzer of 1 m and has operated with a resolving power at the base of the peaks of ∼200 000. Details of current operation are given. The best precision achieved to date is 2.5×10-9, corresponding to ∼250 eV at M = 100 amu; typical precision is ∼5×10-9.
