collision induced dissociation


Also found in: Acronyms, Wikipedia.

collision induced dissociation

A common event in mass spectrometry that follows a collision between an ion and a neutral species, in which part of the ion’s translational energy is converted to internal energy. The internal energy causes dissociation of the ion into smaller ions and may also change its charge.

Moreover, advanced Collision Induced Dissociation (CID) technology enables fragmentation for further confirmation of molecular structure.
Besides the novel Continuous Accumulation of Selected Ions (CASI[TM]) which allows researchers to enrich selectively the signal from a selected protein or one of its large multiply charged fragments, the Bruker FTMS already includes external collision-cell or internal ICR cell Collision Induced Dissociation (CID), as well as Electron Capture Dissociation (ECD) in the ICR cell.
