Membrane permeation is frequently modeled using a vector of relative permeabilities for each component that is permeated. However, no membrane material will have truly uniform permeability; instead, any particular membrane material exhibits variance in physical properties and permeability across its surface. In a very real sense, any single permeating surface can be thought of as a distribution of slightly different membranes as opposed to truly being a single membrane.

Multi-membrane permeation parameters can be fit to existing single-membrane characterization data to produce a more accurate permeation model for any particular membrane material.
