摘要

An ion guide is disclosed comprising one or more layers of intermediate planar, plate or mesh electrodes. A first array of first electrodes is provided on a upper surface and a second array of second electrodes is arranged on a lower surface. An ion guiding region is formed within the ion guide. One or more transient DC voltages or potentials are preferably applied to the first and second array of second electrodes in order to urge, propel, force or accelerate ions through or along the ion guide.

主权项

1. A device comprising:
one or more layers of intermediate planar, plate or mesh electrodes arranged generally or substantially along a longitudinal axis of said device and in a plane in which ions travel in use; a first array of first electrodes disposed on a first side of said one or more layers of intermediate planar, plate or mesh electrodes; and a voltage source arranged and adapted to progressively or sequentially apply one or more transient DC voltages or one or more transient DC voltage waveforms to said first array of first electrodes in order to urge, propel, force or accelerate ions progressively along at least 60% of the longitudinal axis of said device wherein the ions enter and exit the device along the axis.
