| abstract |
An apparatus and method for separating particles dispersed in a fluid. The apparatus includes, in succession, an inlet channel, a constriction channel and an outlet channel, the channels configured to receive a fluid dispersion and to create at the junction of the constriction and outlet channels a fluid dispersion flow having a first flow region and a second flow region, wherein the second flow region has a lower concentration of particles than the first flow region. A collection channel is located at the junction of the constriction and outlet channel to collect fluid from the second flow region. |
