Powder characterization

Gas physisorption

with 3 gases :
Nitrogen : for mesoporosity (pores diameters between 2 nm and 15nm);
Argon : for micropores (diameters inferior to 2nm)
Krypton: for micropores

Mercury porosimetry

for macroporosity : pores dimaters between 20 nm and 200nm.

Granulometry

mastersizer 2000 light diffusion measurement on powder suspensions (0.02µm – 200 µm).
autosizer 4700 90° scattered light by stable particles suspensions (0.003 – 3 µm).
