Fragment Ion
Fragment ions are produced by decomposition of a molecular ion (fragmentation) in the ion source. There exist many kinds of fragment ions, whose distribution reflects the chemical structure of a compound, according to various ways of fragmentation. The fragment ions have smaller masses than the molecular ion.
