The present invention relates to an apparatus and a method for measuring an air-liquid equilibrium partition coefficient, capable of evaluating a vapor-liquid equilibrium partition coefficient and/or a solubility and volatility of a vapor material with respect to various solvents. The apparatus for measuring an air-liquid equilibrium partition coefficient according to the present invention includes: a vapor substance detector having two ports to measure a concentration of a vapor material; a vapor container having two ports to accommodate the vapor material subject to measurement of an air-liquid equilibrium partition coefficient; a solvent container having two ports to accommodate the liquid material subject to measurement of the air-liquid equilibrium partition coefficient; a pipe line to connect the ports of the vapor substance detector, the vapor container, and the solvent container; and a valve provided on the pipe line, wherein the pipe line and the valve are arranged to form a first loop, which disconnects the vapor substance detector from the vapor container and the solvent container, a second loop to connect the vapor substance detector to the vapor container and disconnect the vapor substance detector from the solvent container, and a third loop to disconnect the vapor substance detector from the vapor container and connect the vapor substance detector to the solvent container, so that the valve switches the loops. |
