WebPorosimetry Analysis by Gas Adsorption. Porosimetry is an analytical technique used to determine various quantifiable aspects of a material's porous nature, such as pore … Porosimetry is an analytical technique used to determine various quantifiable aspects of a material's porous structure, such as pore diameter, total pore volume, surface area, and bulk and absolute densities. The technique involves the intrusion of a non-wetting liquid (often mercury) at high pressure into a material through the use of a porosimeter. The pore size can be determined based on the extern…
