A system for determining the zeta potential for characterizing a solid-liquid phase boundary controlled Druckprofilbeaufschlagung

摘要

The apparatus (20) for detecting indicative for a zeta potential information for characterizing an interface between a solid phase and a liquid phase, said apparatus (20) a pressure vessel (1), in which the liquid phase is receivable, a measuring cell (5) which is disposed downstream of and in fluid communication with the pressure vessel (1) can be brought and in which the solid phase is receivable, a reservoir (7), which is arranged downstream of and in fluid communication with the measuring cell (5), a pressurizing means (19 ), which is set up for applying the pressure vessel (1) with a pressure profile with a continuous-time pressure change in such a way that this liquid phase from the pressure tank through the measuring cell (5) into the reservoir (7) is conveyed, and a Erfasseinrichtung (11) for detecting the indicative for the zeta potential information on the measuring cell (5) during of applying the pressure vessel (1) with the pressure profile.
