Suspensions are two-phase systems implying that an interface exists between the surface of the material and the liquid in which it is dispersed. The bulk properties of any suspension are dependent upon – and controlled by - two fundamental parameters: the extent of the particle-liquid interface which is characterized by, for example, particle size; and the nature of that interface, characterized by, for example, surface charge.
The influence of changes in the two parameters permeates every aspect of suspension formulation, testing and manufacture and need to be monitored in order to predict and control suspension behavior. Since surface charge directly affects material performance and processability, measuring zeta potential is a convenient and reliable indicator of its magnitude.
This webinar will explore the importance of using such measurements and its utility in characterizing a variety of industrial materials.
