Method and apparatus for determining the dispersion stability of a liquid suspension

摘要

The present invention relates to a method and apparatus for determining the dispersion stability of a liquid suspension. The method of the present invention includes exposing the liquid suspension to one or more appropriate wavelengths of light while maintaining insoluble particles in the liquid suspension uniformly suspended, and determining the amount of light scattered by the liquid suspension to assess the dispersion stability of the liquid suspension. The present invention also provides an apparatus for carrying out the method of the present invention. The method and apparatus of the present invention can be used, for example, to determine the effect that an additive has on the dispersion stability of a liquid suspension without having to wait for the liquid suspension to phase separate.
