ReproSil-XR 120 Phenyl

Aromatic Selectivity Column for π–π Interaction and Hydrophobic Separations

ReproSil-XR 120 Phenyl from Dr. Maisch HPLC GmbH is a high-purity silica-based HPLC column with a 120 Å pore size and a phenyl-bonded stationary phase. This phase combines aromatic π–π interaction capability with moderate hydrophobic retention, providing unique selectivity for aromatic and conjugated compounds compared to conventional alkyl-bonded phases. Its balanced interaction profile makes it ideal for method development and for separating compounds with subtle structural differences, such as isomers and aromatic derivatives.

ReproSil-XR 120 Phenyl columns from Dr. Maisch HPLC GmbH deliver distinct aromatic selectivity and high performance – the ideal choice for challenging HPLC separations involving aromatic compounds.

Key Features:

  • Fully porous, ultra-pure silica with 120 Å pore size

  • Phenyl bonding – aromatic π–π interaction selectivity

  • Balanced hydrophobic and aromatic retention

  • Excellent reproducibility and resolution

  • Manufactured and QC-tested by Dr. Maisch HPLC GmbH

  • Available in 3 µm, 3.5 µm, 5 µm, and 10 µm particle sizes

Typical Applications:

  • Separation of aromatic pharmaceuticals and metabolites

  • Analysis of phenolic compounds and natural products

  • Method development requiring orthogonal selectivity to C18 phases

  • Resolution of isomers and conjugated systems
