Abstract

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.
