Absorption-enhanced differential extraction device
First Claim
1. A device for enhancing differential transport of desired particles from a sample stream containing said desired particles into an extraction stream, said device comprising:
- a. a sample stream inlet;
b. an extraction stream inlet;
c. a flow channel in fluid communication with said sample stream inlet and said extraction stream inlet for receiving a sample stream from said sample stream inlet in adjacent laminar flow with an extraction stream from said extraction stream inlet;
d. a sequestering material within said flow channel for capturing desired particles in said extraction stream; and
e. at least one outlet in fluid communication with said flow channel.

Abstract
This invention provides an extraction device and a method for extracting desired particles from a sample stream containing the desired particles. The device has a sample stream inlet, an extraction stream inlet, and an extraction channel in fluid communication with the sample stream inlet and the extraction stream inlet. The extraction channel is for receiving a sample stream from the sample stream inlet in adjacent laminar flow with an extraction stream from the extraction stream inlet. A sequestering material within the extraction channel captures desired particles in the extraction stream. A by-product stream outlet in fluid communication with the extraction channel receives a by-product stream comprising at least a portion of the sample stream form which desired particles have been extracted. A product outlet in fluid communication with the extraction channel receives a product which has the sequestering material and at least a portion of the desired particles.
