Characterization Of Emulsions With Acoustic Spectroscopy

Measurement of emulsion droplet size can be accomplished without dilution by the use of acoustic attenuation spectroscopy. This analytical technique can measure emulsions systems at concentrations up to 50% volume, allowing characterization in an as-is state.

Summary

There are many instances of successful characterization of the particle size distribution and zeta potential of emulsion droplets using acoustic spectroscopy. This application note is a repetition to some extent of McClements' work with hexadecane-in-water and water-in-oil emulsions, to show the range of experiments that can be conducted with acoustic measurements.
