The hydrogen and isobutane chemical ionization mass spectra of a number of carotenoids, with symmetrical and unsymmetrical end groups, have been examined. Similar spectra were obtained with each gas. Loss of fragments, characteristic of both the polyene chain and of the end groups were shown by all

## Abstract The uses of dimethyl ether (DME) as an unusual positive ion reagent for chemical ionization mass spectrometry (CIMS) are reviewed. The fragment–molecule adducts formed by ion–molecule reactions of organic substrates with the ionized gas are highly characteristic for the substrates and f
