Electrophoretic Light Scattering (ELS)
Electrophoretic light scattering (ELS) is a technology for measuring electrophoretic mobility via Doppler shifts of the scattered light. When an incident light illuminates dispersed particles that are subjected to an applied electric field, the frequency of the particles’ scattered light will be different from the incident light due to the Doppler effect. The frequency shift is measured and converted to provide the electrophoretic mobility.

Application notes

Measuring the zeta potential of highly concentrated fat emulsion using the BeNano 180 Zeta
In this application note, the zeta potentials of fat emulsion dispersed in water at different concentrations are measured by the BeNano 180 Zeta.


3P Instruments BeNano 90 series nanoparticle size and zeta potential analyzers
The BeNano series is the latest generation of nanoparticle size and zeta potential analyzers designed by Bettersize Instruments. Dynamic light scattering (DLS), electrophoretic light scattering (ELS) and static light scattering (SLS) are integrated in the system to provide accurate measurements on particle size, zeta potential and molecular weight.
