Abstract

A mass spectrometry method comprises: (1) introducing ions and gas into an first electrode section of an ion transport apparatus through a slot of an ion transfer tube, the ion tunnel section comprising a first longitudinal axis that is contained within a slot plane of the ion transfer tube, the first longitudinal axis not intersecting an outlet of the ion transfer tube, wherein the apparatus further comprises: (a) a second electrode section configured to receive the ions from the first electrode section and comprising a second longitudinal axis that is not coincident with the first longitudinal axis; and (b) an ion outlet aperture ;(2) providing voltages to electrodes of the ion transport apparatus that urge the ions to migrate towards the first longitudinal axis within the first electrode section; and (3) exhausting gas through a port that is offset from the ion outlet aperture.
