Definition of mass spectrometry
WebThe mass spectrometer is an instrument designed to separate gas phase ions according to their m/z (mass to charge ratio) value. 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)
