<p>Method for determining the zeta-potential wherein the differential pressure required for the measurement, generated on a measuring interval, is obtained by means of a pump controlled by regulating the rotational speed thereof and wherein the flow potential of the current are measured in synchronism with the differential pressure and wherein the zeta-potential is then calculated in a known manner. With this method, it is possible to reduce the bulk of the apparatus as well as the time required for the measurement of the zeta-potential.</p> |
