COSMOSIL 2.5nNAP 130Å - 2.5µm

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.

• Particle Size 2.5µm
• Naphthalene bonded stationary phase
• Stronger π-π interactions than standard Phenyl Phase
• Low back pressure (compared to Sub 2µm)
• Can be used with any conventional LC Systems
