A mass spectrometer is configured with individual multipole ion guides, configured in an assembly in alignment along a common centerline. 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 vaccum pumping stage hybrid API source-multiple quadrupole TOF mass analyzer.

La présente invention concerne un spectromètre de masse présentant des guides ioniques multipolaires individuels configurés pour former un ensemble aligné le long d'un axe commun. Quatre guides ioniques quadripolaires indépendants (23, 24, 25, 26) et trois segments de guides ioniques quadripolaires plus petits (39, 40, 41) constituant un ensemble linéaire (22) sont positionnés le long d'un axe commun (27) et sont configurés pour former un analyseur de masse à temps de vol, quadripolaire, à sources multiples d'ionisation de pression atmosphérique et à étage de pompage à vide.
