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.
