The cation addition mechanism to polystyrene and the possible interactions between the target plate material and the cationization agent have been studied. A range of different trifluoroacetate salts mixed with DCTB and polystyrene, deposited on several different target plate materials, have been systematically investigated with MALDI mass spectrometry. MALDI-MS yielded polystyrene- and DCTB-Cu adducts when sample solutions were applied on a copper substrate. For silver the same effect was observed. Control experiments showed that these species could only result from laser‐induced redoxreactions between the added salt and the substrate material. Reversed redoxreactions between added salts and target plate material are enabled by laser photon energy input during MALDI experiments.
