WebNov 8, 2024 · The permeability of a membrane can be defined as the passive diffusion rate of permeated molecules across the biomembrane. It is unanimously accepted that permeability of any specific molecule depends mainly on charge number, polarity, size, and to some extent, to the molar mass of the molecule. WebPermeation, Permeance, Water Vapor Permeability Converter. Permeation, in physics and engineering, is the penetration of a permeate (such as a liquid, gas, or vapor) through a solid, and is related to a material’s intrinsic permeability. Permeability is tested by permeation measurement, for example by a minipermeameter.
