Dispersions Characterization

Extensive characterization services are available for both aqueous and non-aqueous dispersions of nanomaterials. NEI has the capability to assess dispersion stability in terms of pH, electrophoretic mobility, zeta potential and viscosity. Further quantitative analysis of dispersion quality is also available, including solids content, rheology, aggregate size, optical transmission, and transmitted haze. Variations in these properties may also be determined as a function of time and/or temperature.
