ResumoThe rigidity of chromatographic packing materials has been evaluated by measuring the swelling during a solvent gradient and plotting the pressure drop across the column. The procedure requires an ordinary liquid chromatograph and can be used routinely for the quality control of packing materials. A derivatization technique is proposed for improving the rigidity of porous polystyrene packing materials.
