Originals Column Liquid Chromatography


A novel biporous poly (glycidyl methacrylate-triallyl isocyanurate-divinylbenzene) resin (denoted as Resin C) was prepared byin-situ co-polymerization with both superfine granules of sodium sulfate and the solvents toluene and n-heptane as porogenic agents. This material is based on a novel porogenic mode of a combination of both solid granules and solvents. The properties of Resin C were characterized, and then compared with both Resin A (where only solvents as porogen) and Resin B (where only solid granules are used as porogen). The biporous resin showed good mechanical performance, high dynamic adsorption capacity and column efficiency at high flow-rates. These factors indicate the biporous resin as a promising adsorbent for high-speed protein separation by chromatography.
