Reversed phase HPLC columns have been widely used because of their superior resolution, high theoretical plate number and ease of use. Since hydrophobic interaction is the dominant separation mechanism in reversed phase chromatography, conventional stationary phases such as C18 and C18 do not offer optimum selectivity for compounds with similar hydrophobicity. COSMOSIL offers a broad selection of columns with unique stationary phases for separation of these difficult analytes. These columns offer improved separation of structurally similar compounds that are difficult to analyse with a C18 type column.

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 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.

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