Can high-resolution sound velocity measurements be used as an analytical tool?

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.

Spectroscopy using light is a familiar technique and the electromagnetic spectrum from UV to IR is routinely employed. This article looks at the advantages and applications of spectroscopy using sound waves, with special reference to pharmaceutical research.
