An MS/MS device created by connecting 3 quadrupole mass spectrometers in
sequence. The first instrument is used for precursor ion selection, the
second as a collision tube for CID or SID, and the third for detection
of fragment ions created by dissociation of precursor ions. CID spectra
of low-energy collisions can be obtained with this instrument.
