Annotation	The applicability of MALDI-TOF MS to the analysis of wax esters (WEs) was investigated. A series of metal salts of 2,5-dihydroxybenzoic acid (DHB) was synthesized and tested as possible matrices. Lithium salt of dihydroxybenzoic acid (LiDHB) performed the best and the sample preparation technique was optimized. WEs showed molecular adducts with lithium [M + Li]+. PSD fragments were used for structure assignment. MALDI with LiDHB was used for several samples of natural origin, including insect and plant WEs.
