We report on a novel matrix-free laser desorption/ionization method named “Desorption Ionization Using Through Hole Alumina Membrane” (DIUTHAME). Simply adding a cationization agent, various organic industrial materials as complex as multi-component ethoxylated hydrogenated castor oil have been successfully mass-analyzed with a very limited fragmentation and no ionization interference in the low mass range.
