Abstract
The invention relates to a method of sorting submillimetric particles entrained in a fluid flowing in an axial direction of a main channel, the particles being of density different from the density of the fluid, and the method being characterized in that it implements, in a first region of the main channel, focusing of the particles along a wall (7) of the main channel (1) by means of at least one focusing device (3), and downstream from said region, collecting of particles in at least one sorting and take-off device (40) in communication with the main channel (1) via an opening such that the particles collected are selected by the take-off device as a function of the size of said particles, and in that said at least one sorting and take-off device is a recirculation chamber (40) in communication with the main channel (1) and presenting at least one recirculation zone (41) for concentrating the collected particles.
