Polymer-based packing materials for reversed-phase liquid chromatography

摘要: Abstract The effects of preparation conditions on the pore structures and chromatographic properties porous polymer gels were studied. diluents in suspension copolymerization methyl methacrylate with a divinyl monomer affected size volume micropores as well those macropores. use non-solvent to such alkanes n-alkyl alcohols resulted smaller volume, accompanied by large Preferential retention rigid, compact solutes was observed due size-exclusion effect micropores. In contrast, better solvation cyclohexanol during polymerization larger leading preferential bulky molecules, while producing macropores volume. also higher cross-linking density.
