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 5PYE | COSMOSIL 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.
