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.
Concentration Range : 0.1-100mg/ml (reference to sample)
Electrophoretic Mobility Range : > ±20μm.cm/V.s
Highest Conductivity : 200mS/cm (reference to sample)
External Size (WxDxH)(mm) : 560x450x300
The photon correlation DLS nanoparticle size and zeta potential analyzer is suitable for the measurement of particle size and surface potential of many different nano emulsions, suspension colloids, etc. It can be widely used in the research and development of fine chemical nanomaterials, surfactants, oligomers, etc. and the quality control of production.
