Small nitrogen oxygen membrane for laboratory
Product Description
Gas separation membranes are very fine hollow fibers through which different mixtures of gases are fed.
As the gases travel through the tubes, a process called selective permeation allows us to separate gases. At a closer look, gas separation membrane, the wall of each of these micro-thin hollow fibers, is an asymmetric filter made of various types of polymer. As different gases travel through the fiber, they come into contact with the membrane and permeate through it. The permeation rate of each gas is determined by its solubility in the membrane material and its diffusion rate. Gases with higher solubility and smaller molecules (fast gases) can pass through the membrane faster than other less soluble gases with generally larger molecules (slow gases). Gases which permeate faster and more are collected outside of the hollow fiber as permeates while gases which do not permeate so well and stay inside of the fiber until they reach the other end are separated out as retentates. Depending on the properties of the desired gas, either or both of permeates and retentates can be used.The permeation rates of different gases and vapors also vary according to the types of polymers used to make membrane fibers. Carefully controlling the material of membrane varies the sorption-diffusion mechanism through the membrane which determines the permeation ra
