The mechanisms of ion formation in matrix-assisted laser desorption/ionization mass spectrometry are still largely unknown. Ions may exist as pre-formed species in the solid state, or may form by ion-molecule reactions initiated by the laser shot, or, most probably, they may originate from a combina
