Nano Particle Size and Zeta Potential Analyzer
Equipment Introduction
The NanoBrook Omni is a Configurable Platform for Particle Sizing and Zeta Potential Measurements. The instrument includes particle sizing and distribution measurements based on the principles of Dynamic Light Scattering (DLS), zeta potential measurements based on doppler velocimetry (electrophoretic light scattering or ELS) and Phase Analysis Light Scattering (PALS) measurements for samples with low mobilities.
