Acoustic spectrometry

Characterization of the particle size distribution in concentrated suspensions or emulsions commonly found in ceramics and construction industry as well as food and cosmetic applications, requires a method to analyze samples in their original concentrations and on a macroscopic scale. This can be achieved by employing acoustic spectrometry, which determines particle sizes in proportion to their respective masses by measuring the damping of ultrasonic waves in concentrated dispersion with particle sizes on the nanometer to micrometer scale.

Color, procession and dispersion characteristics as well as mechanic properties are influenced by particle shape significantly. Furthermore, anisotropic shapes such as rods may exhibit problems when using standard particle size analysis without imaging processes.
