The interpretation of the electron ionization mass spectra of straight-chain and methyl-branched saturated and unsaturated wax esters (WEs) is discussed in this study based on the spectra of 154 standards. The most important fragments indicative of the structure of the acid and alcohol chains are identified and summarized for WEs with various number of double bonds in the chains. The elemental composition of selected important fragments is established from a high resolution accurate mass analysis. The WEs mass spectral database provided in the supplemental data can be used as a reference for the analysis of the GC/EI-MS data.
