Preparatory Column Fractionation of Polymers: Selection of Solvent Gradient

Abstract

The use of a programmable solvent gradient attachment with a high-speed liquid Chromatograph affords a rapid and precise method for evaluating the effects of a variety of solvent gradients on fractionation, a determination of the effect of flow rate on efficiency, and a ready procedure to establish conditions for producing approximately equal amounts of polymer in each fraction. © 1975, Taylor & Francis Group, LLC.
