Particle Size and Zeta Potential

Zeta potential analysis is a technique used to measure the surface charge of particles in a liquid suspension. It indicates the electrostatic stability of colloidal systems — a higher zeta potential (positive or negative) means particles are more stable and less likely to aggregate. Light-scattering technology to determine not only particle size, but also zeta potential, transmittance, molecular mass, and the refractive index of nano- and microparticles in liquid dispersions.
