The origin of ions in matrix-assisted laser desorption/ionization (MALDI) mass spectrometry is currently a matter of active research. A number of chemical and physical pathways have been suggested for MALDI ion formation, including gas-phase photoionization, ion-molecule reactions, disproportionatio
A series of sodium cluster ions, such as Na+(NaCl),, Na'(HCOONa), and Na+(HCOONa),,(CH,C00Na)n2, were observed in electrospray mass spectrometry. These results support the electrophoretic separation mechanism for excess ions at droplet surface, and the charged residue model for gas phase ion formati
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
