Patent ID: 11527396

Abstract:
A multipole with mounting rings arranged on its end faces for mounting the multipole in a mass spectrometer includes two electrode half-shells each having at least two electrodes joinable together by positive-fitting connections on the electrode half-shell longitudinal edges. Each positive-fitting connection includes a fitting and a matching mating fitting, the fitting integrally formed on one electrode half-shell and the mating fitting integrally formed on the other electrode half-shell. Each mounting ring has two mounting ring fittings. One mounting ring fitting can be joined to a mating fitting integrally formed on one of the two electrode half-shells and the other of the two mounting ring fittings can be joined to a mating fitting integrally formed on the other of the two electrode half-shells. Furthermore, a mounting ring for such a multipole has two mounting ring fittings joinable to corresponding mating fittings integrally formed on the electrode half-shells.
