COSMOSIL PYE HPLC Columns

COSMOSIL PYE column is a reversed phase column with 2-(1-pyrenyl) ethyl groups bonded silica packing material. This column utilizes π-π interactions originating from the planar pyrene ring structure to separate structural isomers.

 Main Characteristics

• Separation with high molecular shape selectivity or π- π interactions
• Excellent separation for structural isomers
• Pyrenylethyl group bonded stationary phase

Comparison of π-π Interactions with πNAP

COSMOSIL PYE provides much stronger π-π interactions than πNAP.
