Schematic diagram of tandem mass spectrometry. In tandem mass spectrometry (or MS/MS) ions with the mass-to-charge (m/z) ratio of interest (that is, parent or precursor ion) are selectively reacted to generate a mass spectrum of product ions. CID, collision-induced dissociation; IRMPD, infrared multi-photon photodissociation; SID, surface-induced dissociation.
