Abstract

An ion guide includes a series of electrodes disposed between first and second ends of the ion guide. A power source is configured to simultaneously apply a set of RF voltage waveforms to the series of electrodes, a first set of DC voltages to a first set of electrodes that are adjacent to the first end, and a second set of DC voltages to a second set of electrodes that are adjacent to the second end. The first set of DC voltages is configured to create a first electric field in a first region of the ion guide and the second set of DC voltages is configured to create a second electric field in a second region of the ion guide, the second electric field being uniform across the second region and having an amplitude that is greater than a maximum amplitude of the first electric field.
