Abstract
A system for transporting ions includes: an ion transfer tube having an axis and an internal bore having a width and a height less than the width; and an apparatus comprising a plurality of electrodes, each having a respective ion aperture having an aperture center, the apertures defining an ion channel configured to receive the ions from the ion transfer tube and to transport the ions to an outlet end of the apparatus, wherein at least a subset of the apertures progressively decrease in size in a direction towards the apparatus outlet end, wherein the ion transfer tube is configured such that the ion transfer tube axis is non-coincident with an axis of the ion channel or such that the width dimension of the ion transfer tube bore is parallel to a plane defined by the ion transfer tube axis and the ion channel axis.
