The gas permeability is measured using argon gas in rigid triaxial cells suitable for core diameters of 110 millimeters (L) and 65 millimeters (T).
Side sealing to enhance one-dimensional flow; The surface is overlaid and compressed onto the O-ring.
The test is conducted at 20 ° C.
The circuit is composed of a known upstream control volume as shown in Figure 3.
According to the permeability range of the sample, the volume can be selected from four types.
