Аннотация
A method for the chemical modification (derivatization) of ions obtained by surface assisted laser desorption/ionization (SALDI) is proposed. Derivatization is based on the interaction of desorbed ions with alcohol molecules. The method is simple, does not affect the duration of analysis and ensures the improvement of the analytical characteristics of the SALDI method, when analysis is carried out under the conditions of peak interference and strong fragmentation of analyte ions. The efficiency of the method is demonstrated in the determination of caffeine, pyrrolidine, and diphenhydramine under the conditions of atmospheric pressure sample application.
