Abstract
An ion funnel fabricated from at least three faces that are each formed from a printed circuit board is described. In one aspect the faces are arranged edge to edge and there is provided a set of guard rails proximal to the edges to bias ions away from the edges. In another aspect slots are provided within the circuit board to facilitate an escape of gases from within the funnel.
