Permeationsraten
Web25. feb 2004 · [7] Permeation is commonly viewed as a three-step process. First, gas dissolves into the solid's surface; then it diffuses through the solid; and finally, it desorbs from it. The time dependence of the permeation rate is determined by the diffusion process because the solution and desorption occur on much shorter timescales than the diffusion … WebPermeation is the process of molecular penetration of gases, vapours or fluids through the material membrane of a solid. Permeation rates are inversely proportional to the …

Web1. jún 2003 · If the permeation rate reaches a steady-state level (a constant rate of permeation), the ASTM standard requires that this must be reported. In the test for permeation of formaldehyde through the Biogel Super-Sensitive glove a level of 0.5 µg/cm 2 /min was reached, that being the only steady-state permeation rate attained in these tests.
