HR-US is a nondestructive technique with enormous potential for the analysis of materials and formulations used in the pharmaceutical industry.

This article introduces the application of high-resolution ultrasonic spectroscopy (HR-US) for the analysis of emulsions and suspensions. The authors outline the principles of the technique and illustrate its application for analysis of the crystallization of lysozyme and the formation of a microemulsion.
