57 Zusammenfassung AB [EN] A potential measuring apparatus 100 for determining a physicochemical surface property based on a surface potential at a sample surface 2 of a solid sample 1, like the surface potential and/or a zeta potential of the sample surface 2, comprises a sample support 10 being arranged for accommodating the sample 1, a drop supply device 20 being arranged for placing a liquid probe drop 3 on the sample surface 2, a drop movement device 30 being arranged for providing a sliding movement of the probe drop 3 along a predetermined sliding path 4 on the sample surface 2, an electrode measuring device 40 being arranged for sensing an electrical quantity including at least one of a drop voltage and a drop charge of the probe drop 3 after passing the sliding path 4, wherein the electrode measuring device 40 includes a probe electrode 41 arranged at a downstream end of the sliding path 4 and a measuring circuit 42 coupled with the probe electrode 41, and a calculation device 50 being adapted for determining the physicochemical surface property based on the electrical quantity. Furthermore, a potential measuring method for determining a physicochemical surface property based on a surface potential at a sample surface 2 of a solid sample 1 is described.
