Techniques for Measurements in Concentrated Systems
Vincent A. Hackley
Concentrated suspensions present a number of technical challenges for characterization and monitoring of the solid phase. Recent developments have provided the means to analyze many concentrated systems directly or at solids loadings more closely resembling process conditions. This paper provides a general overview of four techniques: diffusing wave spectroscopy, ultra-small-angle x-ray scattering, acoustic spectroscopy and electroacoustics. Consideration is given to their particular advantages, limitations and applications.
