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.

Multipole with mounting rings arranged on the end faces thereof, and mounting ring of said type

A method manufactures a multipolar electrode device, in particular a multipole for use in a mass spectrometer, wherein the electrode device includes at least one main filter and at least one pre- and/or postfilter. The electrode blanks are separated in several sections for producing the pre- and/or postfilters, which are thereby maintained by a holder in a constant relative position to each other. Moreover, an electrode device may be used in a mass spectrometer and a mass spectrometer may have such a multipolar electrode device.
