description | A system for separating ions includes first and second surfaces extending along first and second perpendicular directions, an ion channel defined between the surfaces and configured to receive a stream of ions, first and second electrode arrays each including a plurality of electrodes extending in a third direction and respectively associated with the first and second surfaces, means for causing gas to flow across the ion channel in a fourth direction substantially opposite the first direction, and a controller configured to apply a DC voltage gradient to the electrode arrays. The electrode arrays are configured to generate an electric field based on the DC voltage gradient. The electric field and the flow of gas are configured to direct ions having mobilities in a first mobility range along a first path and ions having mobilities in a second mobility range along a second path. |
