ION MANIPULATION DEVICE

摘要

An ion manipulation method and device is disclosed. The device includes a pair of substantially parallel surfaces. An array of inner electrodes is contained within, and extends substantially along the length of, each parallel surface. The device includes a first outer array of electrodes and a second outer array of electrodes. Each outer array of electrodes is positioned on either side of the inner electrodes, and is contained within and extends substantially along the length of each parallel surface. A DC voltage is applied to the first and second outer array of electrodes. A RF voltage, with a superimposed electric field, is applied to the inner electrodes by applying the DC voltages to each electrode. Ions either move between the parallel surfaces within an ion confinement area or along paths in the direction of the electric field, or can be trapped in the ion confinement area.

主权项

1. An ion manipulation device comprising:
a. a pair of surfaces; b. arrays of electrodes coupled to the surfaces to which RF potentials are applied to at least one of the surfaces in order to create a pseudopotential that inhibits charged particles from approaching either of the surfaces; and c. simultaneous application of DC potentials to control and restrict movement of ions in between the surfaces.
