<p>This invention provides an extraction device and method for extracting desired particles from a sample stream (2) containing the desired particles. The device comprises a sample stream inlet (1); an extraction stream inlet (5); an extraction channel (7) in fluid communication with the sample stream inlet (1) and the extraction stream inlet (5) for receiving a sample stream (2) from the sample stream inlet (1) in adjacent laminar flow with an extraction stream (4) from the extraction stream inlet (5); a sequestering material within the extraction channel (7) for capturing desired particles (18) in the extraction stream (9); a by-product stream outlet (15) in fluid communication with the extraction channel (7) for receiving a by-product stream (12) comprising at least a portion of the sample stream (2) from which desired particles (18) have been extracted; and a product outlet (14) in fluid communication with the extraction channel (7) for receiving a product comprising the sequestering material and at least a portion of the desired particles (18).</p> |
