Abstract
The present invention is concerned with an ion analysis apparatus comprising an ion guide having an ion optical axis extending from an ion inlet to an ion outlet, the ion guide being configured to guide ions from the ion inlet to the ion outlet along the ion optical axis, wherein the ion guide comprises at least one extraction region located between the ion inlet and the ion outlet, the at least one extraction region being configured to extract ions moving along the ion optical axis of the ion guide in an extraction direction, the extraction direction being substantially orthogonal to the ion optical axis of the ion guide, wherein the apparatus includes ion radial confinement means that in use confine the ions in the radial direction within the ion guide.
