Abstract
Porath and Flodin1 have shown that macromolecules in aqueous solutions may be separated from low molecular weight compounds by liquid chromatography using a cross-linked dextran (‘Sephadex’) as the stationary phase, and water as the mobile phase. It has now been found in these laboratories that polymers dissolved in mineral oil can be separated by a similar Chromatographic technique. Small pieces of thin vulcanized natural rubber latex are used as the stationary phase, and a light paraffin hydrocarbon as the mobile phase.
