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 ?-? interactions.
These columns are recommended for the separation of structural isomers.
Material Characteristics:
COSMOSIL 5PYE
COSMOSIL 5NPE
Silica gel
high purity spherical porous silica
Average particle size
5?m
Average pore size
approx. 120?
Specific surface area
approx. 300m?/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 ?-?
interactions, COSMOSIL PYE achieves excellent separation
of aromatic isomers.
