8. The use of a collision gas to enhance fragmentation is referred to as collision-induced dissociation (CID). It is usually employed in conjunction with one of the metastable or linked scanning techniques. It is possible to distinguish the fragments formed as a result of the collision process from those that would have been formed in any case unimolecular dissociation of precursor ions.
