Surface-induced dissociation
Encyclopedia
Surface-induced dissociation (SID) is a technique used in mass spectrometry
to fragment
molecular ions in the gas phase
by collision of an ion with a surface under high vacuum.
Mass spectrometry
Mass spectrometry is an analytical technique that measures the mass-to-charge ratio of charged particles.It is used for determining masses of particles, for determining the elemental composition of a sample or molecule, and for elucidating the chemical structures of molecules, such as peptides and...

Fragmentation (chemistry)
Fragmentation is a type of chemical dissociation. Fragmentation of a molecule can take place by a process of heterolysis or homolysis.It is a phenomenon observed in mass spectrometry where it is used as a tool to find the structural formula of a molecule, process called structural elucidation.It...
