Cosmosil® PFP
Nacalai Tesque COSMOSIL 5PFP Preparative HPLC Guard Column, 5µm, 120Å, 28mm I.D. x 50mm Length, 1/Pk
Product Number: 13279-51
- Pentafluorophenyl-bonded stationary phase
- Alternative selectivity to C18 columns
- Available in analytical and preparative columns
- Suitable for structural isomers and halogenated compounds
COSMOSIL PFP uses dipole-dipole and π-π interactions. It offers strong retention for compounds with strong dipole moments, e.g. cationic or halogenated compounds. It also has high steric selectivity for structural isomer separations.
