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
