SYSTEMS AND METHODS FOR EXCHANGING SMALL MOLECULES WITH FLUID

Abstract:

An apparatus for exchanging small molecules with a fluid includes a small-molecule conduit for providing a first fluid having a first type of small molecule, a target fluid conduit for providing a target fluid having a second type of small molecule therein, and a carrier fluid conduit for providing a carrier fluid that is configured (i) to receive at least some of the first type of small molecule from the first fluid and transfer at least some of the first type of small molecule to the target fluid and (ii) to receive at least some of the second type of small molecule from the target fluid and transfer at least some of the second type of small molecule to the first fluid. The apparatus further includes an exchange module having an exchange chamber in fluid communication with the small-molecule conduit, the target fluid conduit and the carrier fluid conduit.
