Differentiation of Monoepoxide Isomers of Polyunsaturated Fatty Acids and Fatty Acid Esters by Low-Energy Charge Exchange Mass Spectrometry

Article abstract of DOI:10.1021/ac00275a021

Low-energy charge exchange mass spectrometry is a convenient technique for the unambiguous differentiation of monoepoxide isomers of polyunsaturated fatty acids, fatty acid methyl esters, and fatty acetates.This technique eliminates multistep derivatization procedures which are typically utilized prior to characterization of these isomers with conventional electron ionization mass spectrometry.
