Overview

Nanolink SZ901 series is a new generation of nano particle size and Zeta potential analysis system developed by Truth Optics on the basis of SZ900 scientific research achievements for many years. It uses the principles of dynamic light scattering (DLS) and electrophoretic light scattering (ELS) to measure the nano particle size and Zeta potential respectively, and is widely used in the particle characterization of organic or inorganic nanoparticles, lotion, polymers, micelles, virus antibodies, proteins and other samples, as well as the detection and analysis of sample system stability and particle aggregation tendency.
