Reprospher 200 Phenyl is a reversed-phase HPLC column from Dr. Maisch HPLC GmbH, packed with high-purity, fully porous silica featuring a 200 Å pore size and bonded with phenyl ligands. This aromatic phase provides distinct π–π interaction capabilities, enabling enhanced selectivity for planar, aromatic, and electron-rich analytes — especially in the separation of peptides, protein fragments, and bioactive molecules. The wide-pore structure allows efficient access for larger compounds, while the phenyl surface offers an orthogonal retention profile compared to C18 and C8 phases.
This wide-pore phenyl phase from Dr. Maisch HPLC GmbH is ideal for the selective and reproducible separation of large or aromatic analytes in demanding reversed-phase workflows.
