摘要
A device determines information indicative for a zeta potential at the interface between a solid phase and a liquid phase. The device includes a pressure vessel, in which the liquid phase can be accommodated and a measuring cell, downstream of the pressure vessel and such that it can be brought into fluid communication with the pressure vessel and in which the solid phase can be accommodated. A storage vessel is downstream of and in fluid communication with the measuring cell. A pressure loading apparatus, loads the pressure vessel with a pressure profile with a temporally continuous pressure change so a liquid phase can be conveyed out of the pressure vessel through the measuring cell into the storage vessel. A detection apparatus detects the information indicative for the zeta potential at the measuring cell during the loading of the pressure vessel with the pressure profile.
