multistage mass spectrometry 

CHEMISTRY

An analytical procedure which recognises ions as reactive entities that can be interrogated.

MS/MS instruments consist of two independently operated mass analysers linked by a reaction region in which the ion can be induced to react. Induction often occurs by collision (collision-induced dissociation) in which a selected higher-mass ion dissociates to a smaller fragmented ion. In this simple conceptual instrument, three experiments are possible: precursor ion scan, product ion scan, and constant neutral loss scan. MS/MS recurring over multiple steps is known as MSn. 

Synonyms MS/MS, tandem mass spectrometry
