Deprecated: capillary exit fragmentation, cone voltage dissociation.

Dissociation of an ion as a result of collisional excitation during ion transfer from an atmospheric pressure ion source to the vacuum chamber of the mass spectrometer.

Note 1: This process is similar to ion desolvation but uses higher collision energy.
Note 2: Terms such as cone voltage dissociation and capillary exit fragmentation are design-specific versions of this term, and are deprecated.
