Abstract

Nitrogen transport at 77K through the cylindrical pores in 0.01μm track-etched membranes occurs by a combination of Knudsen diffusion and capillary flow. This transport can be quantitatively predicted without adjustable parameters from a modified form of the theory of Abeles et al. (1991). This implies that some anomalies previously observed for transport with capillary condensation are geometrical artifacts of the heterogeneous pores which were used.
