Aggregate Removal

Hi all, I am looking for chromatographic methods for semi-preparatively separating "monomeric" IgG or Ig-fusion proteins from their multimeric or aggregated forms. I am thinking that HIC and/or IEX should solve this problem, but I cannot easily find good examples of such methods so that I can apply them to my proteins. Does anybody out there have some guidance for me on this? Thanks a million! Chuck in Sunnyvale
