An apparatus for ion manipulations includes an ion manipulation path extending between an inlet and an outlet, at least one continuous electrode configured to receive a first RF voltage signal, and a plurality of segmented electrodes configured to receive a second voltage signal and generate a traveling wave field based thereon. The ion manipulation path includes a first region extending in a first direction, a second region extending in a second direction, and a curved region extending between the first and second regions. The at least one continuous electrode extends through the first region, the curved region, and second region. The segmented electrodes are arranged along the ion manipulation path in the first region, the curved region, and the second region. The traveling wave field is configured to cause ions to travel through, the first region, the curved region, and the second region.
