Sieving coefficient คือ
WebRemoval of middle molecules is highly dependent on convective volume, but also on the pore size of the dialysis membrane, ie, the sieving coefficient must be high enough for the molecule to pass through the dialysis membrane. The total convective transport is a product of convection volume times the sieving coefficient (K =Q uf x S) 6. WebAbstract. Three different sieving coefficient definitions were theoretically investigated. It has been shown that the local sieving coefficient, characterizing membrane property, can …
