ABSTRACT:
The invention provides an apparatus for focusing ions exiting a multipole mass filter. In general terms, the ion focusing apparatus comprises: a housing having an ion entrance and an ion exit, and, contained within the housing: a) a multipole ion guide having an open ion entrance end, and b) a neutral gas. The ion focusing apparatus is configured so that an ion beam enters the housing via the ion entrance and is collisionally focused by the multipole ion guide and neutral gas prior to exiting the housing. The apparatus is readily employed to collisionally focus an ion beam exiting a quadrupole mass filter. Also provided is a mass spectrometry system containing the ion focusing apparatus, and methods employing the same.
