The ZetaViewer ® Nanoparticle Tracking Analysis technology (NTA) allows the quantification and size determination of nanoparticles ranging from 30 nm to 1 µm of diameter by measuring the Brownian motion, of the individual particles. In addition to particle size and concentration the surface charge (zeta potential) can be simultaneously measured.
Calculation of the hydrodynamic particle radius from the brownian motion using the Stockes-Einstein equation.
