Abstract (en)
A mass spectrometer is configured with individual multipole ion guides, configured in an assembly in alignment along a common centreline. A linear (22) of four independent quadrupole ion guides (23, 24, 25, 26) and three smaller quadrupole ion guide segments (39, 40, 41) are positioned along common axis (27) and are configured in a six vacuum pumping stage hybrid API source-multiple quadrupole TOF mass analyzer.
