57AbstractABA 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) for accommodating the sample (1), a drop supply device (20) for placing a liquid probe drop (3) on the sample surface (2), a drop movement device (30) 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) 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) 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.
