Abstract
The invention relates to a microfabricated device for use in measuring the physical properties of compounds, where the properties measured using such devices are those which involve partitioning of the compound between two phases, measuring partition coefficients, distribution coefficients, acid-base dissociation constants, solubility and vapour pressure. The device comprises a microfabricated conduit, in which two fluids flow creating at least two phases between which the compound may partition, and a detector for measuring the amount of compound in each or both fluids.
