Mass spectrometry involves the separation of charged species which are produced by a variety of ionisation methods in LC-MS. These include: • Electrospray Ionisation (EI)

WebbA triple quadrupole mass spectrometer (TQMS), is a tandem mass spectrometer consisting of two quadrupole mass analyzers in series, with a (non-mass-resolving) radio frequency (RF)–only quadrupole between them to act as a cell for collision-induced dissociation. This configuration is often abbreviated QqQ, here Q 1 q 2 Q 3.

WebbMass spectrometry is an analytical method to find the molecular mass of a compound and indirectly helped to prove the identity of isotopes. 1.
