Introduction
The porometry allows determination of the pore size and pore size distribution of pores that are actively contribution to the filtration process. The technique gives quantitative information on the membrane morphology.
Principle
Capillary flow porometry (CFP) uses the displacement of a wetting liquid inside a porous structure by means of an inert gas flow. The pore size can be calculated according to the applied pressure with the Young-Laplace equation: rρ = 2 * γ * cos(θc) / ΔP
Pores open as pressure increases starting with the biggest pores. Once the liquid is out of the pores, the dried membrane is measured to ensure no morphology change.
Applications
• Microfiltration/Ultrafiltration membrane characterization
• Membrane permeability
• Material defects assessment
Conditions determination with:
• PES (Polyethersulfone) membrane disk (25 mm)
• Perfluoroether (Porefil®) as wetting liquid
