On the formation of artefact peaks in linked scans of the magnet and electric sector fields in a mass spectrometer

Abstract

The apperrance of peaks at non‐integral masses in linked scans, where the ratio B/E is kept constant, is shown to be caused by fragmentations of metastable ions occuring in the region between the magnetic and electric sectors. A formula is given for calculating the mass of the parent metastable ion and that of its daughter ion.
