More Information
Summary:A system to facilitate separation and concentration of particles based on centrifugal force on suspended particles, including biological matter, which are made to flow in a vortex structure is provided. The centrifugal force urges larger particles to collect along outer portions of the vortex flow. Conversely, within a vortex structure, a radial hydrodynamic pressure drop is also amplified to urge smaller particles toward inner portions of the vortex flow. This force created by the pressure can reach magnitudes that encourage a sharp cut-off and improved resolution discrimination between particle sizes. Thus, separated streams of particles can be collected with both increased concentration and purification.
