Patent number: 6124592Abstract: An apparatus and method to separate and store ions by exploiting mobility characteristics of the ions. A sample is introduced into a trap volume and ionized. The ions are separated according to their mobility characteristics by applying an electric field to the trap volume. The ions thus migrate to equilibrium positions in the trap volume due to a difference in mobilities and to changes in the electric field. The ions may be sequentially scanned from the trap by changing the electric field. The identity of ions within the trap may then be determined.Type: GrantFiled: March 18, 1998Date of Patent: September 26, 2000Assignee: Technispan LLCInventor: Glenn E. Spangler
