Abstract
Disclosed is an ion guide for transferring ions from and ion source through vacuum regions in a mass spectrometer. The ion guide includes a housing with insulating holders provided to secure electrode rods of multiple devices in longitudinal alignment for the transmission of ions from the ion source to a mass analyzer. The device comprise a plurality of electrode rods each having at least one connecting leg. The rods are connected to the insulating holders via these connecting legs using connecting plates mounted on either side of and adjacent to each insulating border such that the connecting plates are in electrical contact with connecting legs. The connecting plates also have positioning groves to hold the connecting legs in position such that electrical contact is maintained between groups of the electrode rods.
