What is zeta potential?
Zeta potential is the amount of electrical charge on the surface of a particle. The charge is an important characteristic that affects the degree of dispersion or aggregation of particles in a solution. When the absolute value of zeta potential is large the solution is more stable. The particles are more likely to remain dispersed and less likely to aggregate. The value of zeta is also very sensitive to surface chemistry. As a result, it is an ideal indicator for detecting contamination or for monitoring adsorption on the particle surface.
