COSMOSIL PYE and COSMOSIL 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.

 COSMOSIL 5PYECOSMOSIL 5NPE
Silica gel high purity spherical porous silica
Average particle size 5µm
Average pore size approx. 120Å
Specific surface area approx. 300m²/g
Stationary phase 2-(1-pyrenyl)ethyl group nitrophenylethyl group
End capping treatment near-perfect treatment

 

Separation of PAHs

Due to the planar pyrene ring structure and strong π-π interactions, COSMOSIL PYE achieves excellent separation of aromatic isomers.

Advantage of dipole-dipole interactions

COSMOSIL NPE retains 1, 8-dinitronaphthalene longer than 1, 5-dinitronaphthalene due to the dipole-dipole and π-π interactions.
