Membrane selectivity for an aqueous system by dynamic osmometry |
|
| Authors: | Howard Sheffer Paul Sumner |
| Abstract: | Commercial and fractionated samples of poly(ethylene glycol) and a sample of Dextran were used as standards to show the limitation of a cellulose acetate membrane for osmotic pressure determination of molecular weight in an aqueous system. The leakage of this membrane was much greater in the aqueous system than in organic solvents. |
