Abstract
Multipole rod assemblies for guiding or trapping ions in a mass spectrometer. A multipole rod assembly includes a plurality of modules. Each module includes a shield element, one or more insulating elements coupled to the shield element, and one or more multipole rods mounted on the insulating elements, wherein the modules are coupled together to form the multipole rod assembly such that the multipole rods of the modules define an interior volume for guiding or trapping ions.
