The conduitalso has at least one side wall surrounding an ion transfer channel. The side wall includes a plurality of aperturesformed in the longitudinal direction of the side wall so as to permit a flow of gas from within the ion transfer channelto a lower pressure region outside of the side wall of the conduit
