Abstract

A separation medium for removing small molecules from biomacromolecule in aqueous mixtures comprises gel filtration chromatography beads having a nominal protein fractional range of about 1000 Da to about 5000 Da and having an internal adsorbent matrix derived from a hydrophobicized scaffold. The gel filtration chromatography beads remove small molecules that are less than 1500 Da and have log Pow values greater than about −0.5 from biomacromolecules in aqueous mixtures. Devices containing the separation medium are also provided.
