Abstract
A mass spectrometry method comprises: (a) introducing ions and gas into a first electrode section of an ion transport apparatus along an axis, the ion transport apparatus further comprising a second electrode section including: a plurality of stacked, mutually parallel ring or plate electrodes; and an ion outlet aperture configured to receive the ions from the second electrode section and to transfer the ions to the vacuum chamber; (b) providing only non-oscillatory voltages to electrodes of the first electrode section of the ion transport apparatus that divert motion of the ions away from that axis and towards an entrance aperture of the second electrode section; (c) transporting the ions through the second electrode section to and through the ion outlet aperture to the vacuum chamber; and (d) removing a major portion of the gas through an exhaust port that is offset from the ion outlet aperture.
