COSMOSIL NPE Nitrophenylethyl Columns

COSMOSIL PYE (Pyrenylethyl group bonded) and COSMOSIL NPE (Nitrophenylethyl group bonded) column show unique retention characteristics based on multiple separation modes such as hydrophobic, charge transfer and π-π interactions. These columns are recommended for the separation of structural isomers.

  • Nitrophenylethyl group bonded stationary phase
  • Separation with dipole-dipole and π-π interactions
  • Excellent separation for structural isomers
