WebMecadi focuses on customer-specific permeation measurements. While reliable measuring equipment for water, carbon dioxide and oxygen is available and established, the … In physics and engineering, permeation (also called imbuing) is the penetration of a permeate (a fluid such as a liquid, gas, or vapor) through a solid. It is directly related to the concentration gradient of the permeate, a material's intrinsic permeability, and the materials' mass diffusivity. Permeation is modeled by … See more The process of permeation involves the diffusion of molecules, called the permeant, through a membrane or interface. Permeation works through diffusion; the permeant will move from high concentration … See more Abbé Jean-Antoine Nollet (physicist, 1700–1770) Nollet tried to seal wine containers with a pig's bladder and stored them under water. After a while the bladder bulged outwards. He noticed the high pressure that discharged after he … See more • Moisture vapor transmission rate – Measure of the passage of water vapor through a substance • Oxygen transmission rate – measure of packaging permeability • Carbon dioxide transmission rate See more • Permeant: The substance or species, ion, molecules permeating through the solid. • Semipermeability: Property of a material to be permeable only for some substances and not for others.
