ReproSil 70 Phenyl

Small-Pore Phenyl Column for Aromatic and Small-Molecule Separations

ReproSil 70 Phenyl from Dr. Maisch HPLC GmbH is a fully porous, high-purity silica HPLC column with a 70 Å pore size and a phenyl-bonded phase. This stationary phase combines hydrophobic interactions with π–π aromatic selectivity, making it ideal for the separation of aromatic compounds, structurally related isomers, and small molecules. The small pore size ensures high surface area, delivering sharp peaks, high efficiency, and excellent reproducibility for routine and method development applications.

ReproSil 70 Phenyl columns from Dr. Maisch HPLC GmbH deliver aromatic selectivity with small-pore efficiency – the ideal choice for high-resolution small-molecule HPLC separations.

Key Features:

  • Fully porous, ultra-pure silica with 70 Å pore size

  • Phenyl bonding – USP L11 classification

  • π–π interactions for aromatic and conjugated analytes
