Although zeta potential measurements are commonly used to measure colloidal suspensions or molecular solutions, it is also possible to measure the zeta potential of planar surfaces. This webinar introduces the concept of surface zeta potential, shows how it can be measured on the Zetasizer Nano using the surface zeta potential cell and discusses some recent applications.
