Abstract

Low-energy charge exchange mass spectrometry Is a convenient technique for the unambiguous differentation of monoepoxide isomers of polyunsaturated fatty acids, fatty acid methyl esters, and fatty acetates. This technique eiimlnates mutlistep derivatlzatlon procedures which are typically utilized prior to characterization of these Isomers wlth conventional electron Ionization mass spectrometry,
