Granulometry is the determination of the particle size distribution of a sample. The particles in question may be in granular or powder form, or even dispersed in a liquid phase.


There are many granulometry techniques. The technique chosen depends on several factors, including the size of the particles to be analyzed:

  • Sieving
  • Centrifugation
  • Laser granulometry (dry or wet process)
  • Microscopy
  • Zeta potential
The choice of the proposed particle size method will be adapted to your samples
