WALLIS is an innovative zeta potential analyzer dedicated to the characterization of nanoparticle suspensions . It is based on a revisited and modern version of the Laser Doppler Electrophoresis (LDE) technique offering a unique and unequaled measurement resolution. It is complementary to the Cordouan’s VASCO particle size analyzer to study colloidal solution stability and properties.
Zeta potential is a fundamental properties of colloidal suspensions. Basically is intimately related to the number of electrical charges attached to the surface of the particles when immersed in a solvent. It is thus linked to particle-particle interaction and formulation stability in a very complex way described by physical models like the Electrical Double Layer (EDL).
