COSMOSIL PYE HPLC Columns

COSMOSIL PYE StructureCOSMOSIL 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
