Abstract

Doubly charged ions are rarely encountered in desorption techniques. For divalent ions, the production of singly charged species by clustering with counterions, decomposition and one-electron reduction are generally observed. Doubly charged ions are, however, observed more frequently in field desorption than in other desorption methods, indicating the importance of the field in their extraction from the surface. The observation of doubly charged ions might therefore be used as a probe of field effects in desorption mass spectrometry.
