Patent ID: 8387803

Claim:
A particle sorting system, comprising: a particle sorting cell, in turn comprising: a cavity; an inlet of a fluid flow into said cavity; a first outlet of a first part of said fluid flow out from said cavity; a second outlet of a second part of said fluid flow out from said cavity; whereby said fluid flow has a flow direction between said inlet and said first and second outlets; said second outlet being displaced from said first outlet in a first direction transverse to said flow direction; an acoustic generator, arranged to apply an acoustic standing wave in a separation zone of said fluid flow within said cavity; said standing wave being transverse to said flow direction as well as to said first direction; and a controller, arranged to control a selective operation of said acoustic generator in dependence of an input data signal associated with a particle comprised in said fluid flow, whereby said particle selectively can be separated into said first outlet or said second outlet; a flow provider, fluidly connected to said inlet and arranged for providing a continuous laminar fluid flow into said cavity; said fluid flow having a physical property interface, said physical property interface having a normal directed perpendicular to a flow direction and essentially perpendicular to said acoustic standing wave; said flow provider being further arranged for providing particles in said laminar fluid flow adjacent to said physical property interface and separated in said flow direction; a detector arranged for detecting at least one of particle properties and numbers of particles of said fluid flow, and for supplying said controller with said input data signals in response to said detected at least one of particle properties and numbers of particles.
