Zeta Potential / Elektroakustik und ELS

Determination of Zeta potential

The zeta potential is an indicator of the stability of a dispersion and the mobility of its particles in external fields. A characteristic value is the isoelectric point (IEP, zeta potential = 0 mV), at which the particles agglomerate and the system precipitates. The DT-300 and DT-310 instruments determine the zeta potential of highly concentrated dispersions using the electroacoustic method. The BeNano instruments measure the zeta potential of nanoparticles via electrophoretic light scattering (ELS).
