Claim:
1. A system for separating particles of interest from a sample, the system comprising: one or more acoustic transducers sources; a flow cell acoustically coupled with the acoustic transducer source, the flow cell having a flow channel therethrough for receiving and conducting a sample; wherein the acoustic transducer sources is positioned and configured to deliver a standing wave transverse to the flow channel, the standing wave having at least one pressure node and adjacent pressure antinode; and wherein a centerline of the flow channel is offset from positioned between the at least one pressure node and pressure antinode of the standing wave such that a pressure gradient extends transverse to the centerline of the flow channel when the acoustic transducer delivers the standing wave; wherein the standing wave delivered by the acoustic transducer includes only one pressure node or pressure antinode, and wherein the flow channel is offset from a centerline of the flow cell.
