Abstract: An apparatus for the separation of oppositely charged ions comprises a body including an inlet fluidly coupled to a first outlet and a second outlet. A flow director including a discharge is disposed in the body between the inlet and the first and second outlets. The flow director is configured to fluidly couple the inlet and the first and second outlets. The flow director discharge is proximate to the first and second outlets. A magnetic field is orthogonal to the flow director discharge and the magnetic field is located between the flow director and the first and second outlets. The magnetic field is configured to separate the oppositely charged ions.
