Abstract
The present invention relates to an improved apparatus and method for assembly for a cylindrical split-flow thin separation channel that is capable of continuously separating particles of interest from a suspension flowing through the channel. The apparatus provides better precision in the separation process by providing better flow characteristics at the inlet, outlet, and in the zone of separation. Splitter surfaces are provided that match the calculated theoretical Inlet Splitter Surface (ISS) and Outlet Splitter Surface (OSS). A flow distributor diverts the inlet carrier flow into a stable, circumferentially uniform, laminar annular flow. The design enables manufacturing and assembly methods to ensure precise alignment of the components to further improve the flow profiles within the separation channel and to ensure repeatability device-to-device.
