Particle Size

Fully automated analysis of particle size distribution and particle shape analysis

One of the most fundamental measurements for the particle technologist is the measurement of particle size distributions. While the concept of ‘particle size’ is a simple one to understand, the practice of obtaining reliable and accurate particle size measurement and distribution is more complex. Particles are rarely simple geometric shapes, and describing an irregular shape and converting this into a ‘size’ is a challenging task. Couple this with the fact that particles may cover a wide range of sizes; from nanometres to millimetres, and the complexities of obtaining good dispersions of particles, and a picture starts to emerge of the difficulties involved in obtaining reliable particle size data.

Quantachrome UK offers a range of advanced particle size analysis techniques, and we support these with a team of highly trained and experienced technologists to help identify the most suitable technique for a given application.

Laser diffraction analysis: Cilas’ range of laser granulometers can quickly and simply determine the full particle size distribution of particles in both LIQUID DISPERSION and DRY POWDERS.
Image analysis and Shape analysis: Cilas analysers can be equipped with advanced imaging and shape analysis capabilities to give detailed information on particle shape factors and visual inspection of particles.
Analysis of concentrates and nanoparticles. Dispersion Technology’s range of acoustic analysers allow the analysis of highly concentrated particle suspensions without the need for dilution, and the analysis of particles down to the nanometre level.
