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.
