Mass spectrometry animation of SRM : – ions of 3 different masses (ie colors) start in the first quadrupole ; – one ion of a selected mass (ie blue color) is filtered in Q1 ; – then fragmented in q2 into 3 different fragments (with different masses, ie shapes) ; – one of these fragments is filtered in Q3. – this selected fragment hits the detector after Q3 and produces a signal (ie flash). Please check www.cruxgraphix.ch for details.

Yes : in this case Q1 is a quadrupole “filtering” one mass, q2 is a second one used for the fragmentation, and Q3 is a third one also filtering. (Note : in the nomenclature, a big “Q” should be used for a quadrupole with a mass-filtering capability, and a small “q” should be used for a quadrupole “transmitting” the ions – in that case along fragmentation.)
are Q1,2&3 quadrupoles
