Other particle size measurement techniques

The majority of industrial materials and products consist of powders and particles. Particle size measurement, i.e. information on particle size distribution and particle shape is important for a better understanding on the physical characteristics of powders that influence the behavior during handling and processing, like flowability, transport and storage.

The characterization of size distribution and shape is a strong tool in R&D and Quality Control environment and makes particle characterization important in various areas such as: crystal growth, ceramic and alloy properties, emulsions stability, catalyst activity, paint performance, wastewater management, and so on.

Besides light scattering techniques such as Laser Diffraction and Photon Correlation Spectroscopy, also more conventional sizing techniques such as Electrical Sensing Zone, Sedimentation and Sieve analysis are available in our laboratory for particle size measurement. Each sizing technique has its own range of applicability for particle size measurement, depending on particle size range and nature of the powder or particles under investigation.
