COSMOSIL 5PYE Guard column, 120Å, 5 µm, 4.6 mm ID x 10 mm

COSMOSIL PYE column is a reversed phase column with 2-(1-Pyrenyl) ethyl groups bonded silica packing material. COSMOSIL PYE shows a unique retention characteristics based on multiple separation modes such as hydrophobic and π-π interactions. This phase utilizes π-π interactions originating from the planar pyrene ring structure to separate structural isomers.

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