Abstract
The invention relates to an ion guide consisting of RF multipole segments to transfer ions from an ion source into a mass analyzer. The invention consists in having movable RF multipole segments in the ion guide which extend or electrically connect other RF multipole segments along the axis of the ion guide, in which spaces have arisen as a result of a change in configuration of the mass spectrometer, comprising ion source, ion guide and mass analyzer. The moved RF multipole segments bridge the spaces which have arisen between the components of the mass spectrometer and facilitate the transfer of the ions from the ion source to the mass analyzer.
