摘要： A method of determining a phase separation concentration of a sample substance in a solution, comprises the steps of measuring values of a physical quantity of the solution containing the sample substance with at least one sample substance concentration lower then the phase separation concentration, wherein the physical quantity characterizes an interaction of the solution with sound waves, determining a concentration function representing a dependency of the physical quantity on the sample substance concentration lower then the phase separation concentration, and determining the phase separation concentration as a concentration value at which the concentration function equals a predetermined critical value of the physical quantity of the solution containing the sample substance in a saturated condition. Furthermore, a concentration determining device is described.
