Solid surface analysis is important for determining electrokinetic potential of macroscopic solids where streaming potential and currents are measured. The instrument is capable of acquiring single measurements at a specific pH or a titration, which can range for pH 2 to 12. With the availability of three mounts, a variety of samples ranging from solid surfaces to fabrics and powdered samples can be assessed.The electrokinetic analyser can measure surface potential (zeta potential) of smooth surfaces and Isoelectric point of surfaces can also be identified. Surface potential of metal plates, ceramic tiles, wafers and thin films can be measured with a clamping cell whereas for measurements of polymer membranes, filters textile fabrics and minerals and rocks require an adjustable gap cell. A cylindrical cell can be acquired for measuring zeta potential of powdered and granular samples.
