Photon Correlation DLS Nanoparticle Size and Zeta Potential Analyzer

Testing Principle of Photon Correlation DLS Nanoparticle Size and Zeta Potential Analyzer

Using the principles of electrophoretic light scattering and photon correlation spectroscopy, the magnitude of a particle's zeta potential is determined from the speed of the particle's electrophoretic motion in a liquid. The overall velocity of the electrophoretic motion of the particles and the amount of doppler shift of the scattered light caused by laser irradiation of these particles are varied. Photon correlation spectroscopy analyses the magnitude of the particle zeta potential based on the frequency shift.
