Tandem mass spectrometry

A quadrupole time-of-flight hybrid tandem mass spectrometer.

Triple quadrupole diagram; and example of tandem mass spectrometry in space.

An ion trap mass spectrometer is an example of a tandem mass spectrometry in time instrument.

Tandem mass spectrometry, also known as MS/MS or MS, involves multiple steps of mass spectrometry selection, with some form of fragmentation occurring in between the stages. In a tandem mass spectrometer, ions are formed in the ion source and separated by mass-to-charge ratio in the first stage of mass spectrometry (MS1). Ions of a particular mass-to-charge ratio (precursor ions) are selected and fragment ions (product ions) are created by collision-induced dissociation, ion-molecule reaction, photodissociation, or other process. The resulting ions are then separated and detected in a second stage of mass spectrometry (MS2).
