COSMOSIL nNAP Series (Napthylethyl group with stronger n-n Interaction than Phenyl)

COSMOSIL πNAP is a reversed phase HPLC column with Naphtylethyl group bonded silica packing material. The naphthylethyl group is composed of two fused aromatic rings and forms strong π-π nteractions with unsaturated compounds. This column offers improved separation of compounds such as positional isomers that are difficult to analyze with alkyl group bonded materials.

• Naphthalene bonded stationary phase
• Stronger π-π interactions than standard Phenyl Phase
