Physical gas adsorption techniques and mercury porosimetry allow the characterisation of porous solids texture. Gas adsorption/desorption curves at constant temperature (isotherm) allow the surface area and pore size distribution determination among others in micro-mesoporous solids . High-pressure mercury intrusion allow the determination of the porosity of the materials showing accessible pores in the range of 1 micrometer to 1 mm.

Measurements

Determining the specific surface area of powder by one-point method.
Nitrogen adsorption-desorption isotherm, at 77K, are recorded taking into account the nature of the solids. Standard degassing conditions are 120 ºC during 12 hours (indicate if other conditions are required). By analysis of the relative pressure zone up to 0.35 and application of the BET method to the results.
Pore size analysis, on porous solids, by mercury intrusion from 3 microns to 940 microns as standard and provides software for more advanced operations.
