COSMOSIL Protein Separation HPLC Columns

COSMOSIL offers a variety of stationary phases with wide-pore silica gel material for separations of polypeptides and proteins. The following wide pore type reversed phase columns are available:

  • C18-AR-300: Octadecyl Group 
  • C8-AR-300: Octyl Group 
  • C4-AR-300: Butyl Group 
  • Ph-AR-300: Phenyl Group
  • Protein-R: Octadecyl Group

COSMOSIL Protein-R is a reversed phased HPLC column designed specifically for peptide and protein separations. This column provides improved separation, high recovery rate and acid-resistant, which are often problematic to separate using conventional C18-300Å (wide pore) and C4-300Å (wide pore).
