Abstract:
A system for the determination of at least one physicochemical property of a compound which comprises:(i) a microfabricated device having an internal surface defining a first conduit; p1 (ii) a first fluid through said first conduit, said compound being present in the first fluid; (iii) a second conduit in said microfabricated device; (iv) a second fluid flowing through said second conduit, said second fluid being non-miscible with said first fluid; (v) one or more restricted openings being present between the first and second conduits to allow contact between the first and second fluids at the one or more restricted openings via a partition interface formed between the first fluid and the second fluid, the partition interface being formed by contact between the first fluid and the second fluid; (vi) a detector for measuring the amount of the compound present within the first fluid or the second fluid or both; wherein presence of compound in either the first fluid or the second fluid or both is measured to determine the physicochemical property due to the partitioning of the compound through the partition interface.
