Abstract: In one aspect, an ion guide for use in a mass spectrometer is disclosed, which comprises a first plurality of conductive electrodes disposed on a first surface, a second plurality of conductive electrodes disposed on a second surface, wherein the two surfaces are positioned relative to one another and shaped so as to provide a passageway having an inlet for receiving an ion beam and an outlet through which target ions of interest exit the passageway. The ion guide further includes an orifice formed in at least one of those surfaces through which neutral species and/or large ion clusters, when present in the ion beam, exit the ion guide.

Abstract: In one aspect, an ion guide for use in a mass spectrometer is disclosed, which comprises a pair of printed circuit boards (PCBs) having an inlet for receiving a plurality of ions from an upstream ion source and outlet through which the ions exit the ion guide. The ion guide includes at least two ion paths provided in the space between the two PCBs for transmission of ions from the inlet to the outlet. The ion guide can further include at least one ion-routing device that can be coupled to the ions paths for selecting a propagation path of the ions between those ion paths. In some embodiments, the two ion paths can have at least one segment in common.

Abstract: An ion mirror for use in a time-of-flight mass spectrometer includes a mirror ring sub-assembly for creating an electric potential field to decelerate incoming ions and accelerate outgoing ions, and a grid sub-assembly comprising one or more grid plates, which define bounds of the electrical potential field of the ion mirror. The mirror ring sub-assembly and the grid sub-assembly are coaxially superposed, and the mirror ring sub-assembly is mechanically engaged with the grid sub-assembly only at one of the grid plates.
