A hybrid mass spectometer is an instrument which combines analysers of different types, e.g. magnetic plus electric sector combined with quadrupole. The study of ions involving two stages of mass analysis has been termed mass spectrometry\/mass spectrometry.","links":[{"term":"mass spectrometry","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/M03746"}],"sources":["PAC, 1991, 63, 1541.
