  2. Capillary flow porometry - Wikipedia

    en.wikipedia.org/wiki/Capillary_flow_porometry

    It is widely used to measure minimum, maximum (or first bubble point) and mean flow pore sizes, and pore size distribution in membranes [1] nonwovens, paper, filtration and ultrafiltration media, hollow fibers, [2] ceramics, etc. In capillary flow porometry an inert gas is used to displace a liquid, which is in the pores. The pressure required ...

  3. Porosimetry - Wikipedia

    en.wikipedia.org/wiki/Porosimetry

    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 ...

  4. Pore structure - Wikipedia

    en.wikipedia.org/wiki/Pore_structure

    Micro CT of porous medium: Pores of the porous medium shown as purple color and impermeable porous matrix shown as green-yellow color. Pore structure is a common term employed to characterize the porosity, pore size, pore size distribution, and pore morphology (such as pore shape, surface roughness, and tortuosity of pore channels) of a porous medium.

    en.wikipedia.org/wiki/Thermoporometry_and...

    NMRC is a recent technique (originated in 1993) for measuring total porosity and pore size distributions. It makes use of the Gibbs–Thomson effect: small crystals of a liquid in the pores melt at a lower temperature than the bulk liquid : The melting point depression is inversely proportional to the pore size.

  6. Nuclear magnetic resonance in porous media - Wikipedia

    en.wikipedia.org/wiki/Nuclear_magnetic_resonance...

    It makes use of the Gibbs-Thomson effect : small crystals of a liquid in the pores melt at a lower temperature than the bulk liquid : The melting point depression is inversely proportional to the pore size. The technique is closely related to that of the use of gas adsorption to measure pore sizes (Kelvin equation).
