COSMOSIL NPE HPLC Columns

Cosmosil® PYE and NPE

Specialty for Structual Isomers / π-π interaction, charge transfer and stereo selectivity

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
