Principle

A wetting liquid is allowed to spontaneously fill the pores in the sample and a nonreacting gas is allowed to displace liquid from the pores. The gas pressure and flow rates through wet and dry samples are accurately measured. The gas pressure required to remove liquid from the pores and cause gas to flow is given by

D = 4 γ cos θ / p

where D is the pore diameter, γ is the surface tension of liquid, θ is the contact angle of liquid, and p is the differential gas pressure. From measured gas pressure and flow rates, the pore throat diameters, pore size distribution, and gas permeability are calculated.

Capabilities

● Diameter of the most constricted part of a through pore (pore throat)

● Mean flow pore diameter (50% of flow is through pores smaller than the mean flow pore)

● Bubble Point (the largest through pore throat diameter)

● Pore diameter range

● Pore distribution:

· f = -d[(fw/fd) x 100] / dD

· fw = flow rate through wet sample

· fd = flow rate through dry sample

● Gas permeability in many desired units including Frazier, Gurley, Rayl & Darcy
