ABSTRACT:
The invention provides a multipole device for a mass spectrometer system. In general, the multipole device contains a plurality of conductive rods each comprising a conductive layer, a resistive layer, and an insulative layer between the conductive and resistive layers. The invention finds use in a variety of applications, including ion transport, ion fragmentation and ion mass filtration. Accordingly, the invention may be employed in a variety of mass spectrometer systems.
