The particle size distribution is determined through a combination of laser diffraction and PIDS (polarization intensity differential scattering). The laser scattering enables a determination of particle sizes in a range of 40 nm to 2 mm.
Two models according to Mie or Frauenhofer are available for mathematical assessment of the results. For precise evaluations, tabulated refraction indices are provided or can be measured in the laboratory.
The measuring cell is solvent-resistant; this means that solvent-based dispersions can be measured, as well. The device is used for research and education.
Typical applications at the the Lucerne School of Engineering and Architecture:
- Phase change dispersionen
- Personal care products such as lotions, creams, emulsions, sunscreen products
- Paints and lacquers
- Coating with nanoparticles
- any many more...
