4. Granulometric and morphological analysis techniques

Numerous methods and principles exist for determining the particle size of dispersed systems, detailed descriptions of which can be found in several reference works (e.g. ref. ). The main techniques are :

• sieving ;

• microscopy and image analysis ;

• sedimentation ;

• meter with resistance variation ;

• optical techniques (diffraction, dynamic, static or multiple scattering, absorption, backscattering of light, transition time, extinction time, etc.);...
