Porosimetry
When to choose this option: You need pore size distribution, total pore volume, median pore diameter and/or sample density (meso- and macropores), or through-porosity of sheets, membranes and filters.
Porosimetry covers several complementary techniques for measuring the size, volume and distribution of pores within a material’s structure: mercury intrusion, capillary flow porometry (measuring through-porosity), and gas adsorption (micro- and mesopores – see the “BET Surface Area” option). Micromeritics covers meso- and macropores with mercury porosimetry (AutoPore V), and the through-porosity of sheets, membranes and separators with capillary flow porometry (AccuPore); for micro/mesoporosity analysis by gas adsorption (incl. overlap with the BET measurement), see the 3Flex and ASAP series under the “BET Surface Area” option.
Which instrument should you choose?
- Through-porosity of sheets, membranes, separators or filters (bubble point, mean flow pore, through-pore size distribution) – without mercury → AccuPore
- Pore size distribution, total pore volume and/or sample density (powder, granules, porous solid material, meso- and macropores) – mercury porosimetry → AutoPore V
- Micro- and mesoporosity analysis, or BET surface area on the same sample → 3Flex / ASAP series (see the “BET Surface Area” option)
