The technique of laser diffraction particle sizing uses the principles of static light scattering (SLS) and Mie theory to calculate the size of particles in a sample: particles passing through a laser beam will scatter light at an angle that can be directly related to their size. These could be suspensions of solid particles, emulsion droplets, or even dry powders. This method is effective under the assumption that all particles being analysed are of a spherical morphology.
Malvern Mastersizer 2000
- Particle size distribution by laser diffraction
- Large volume sample dispersion unit - Hydro 200MU
- Limitations: particle sizes < 1µm; non-spherical particles and materials with a low refractive index with respect to the dispersive medium
- Solutions usually in the order of 1 %w/v
