On the Primary Ionization Mechanism(s) in Matrix-Assisted Laser Desorption Ionization

A mechanism is proposed for the first step of ionization occurring in matrix-assisted laser desorption ionization, leading to protonated and deprotonated matrix (Ma) molecules ([Ma+H]+ and [Ma-H]- ions). It is based on observation that in solid state, for carboxyl-containing MALDI matrices, the mol...
