Reprospher 100 Phenyl-Hexyl is a reversed-phase HPLC column from Dr. Maisch HPLC GmbH, based on high-purity, fully porous silica with a 100 Å pore size and bonded with phenyl-hexyl ligands. This unique phase combines strong hydrophobic interaction from the hexyl chain with π–π selectivity from the terminal phenyl ring, enabling highly specific separations of aromatic, hydrophobic, and structurally similar compounds. Compared to classical phenyl or C18 phases, this column offers improved resolution of planar analytes, halogenated substances, and positional isomers — especially useful in pharmaceutical, environmental, and food analysis.
Reprospher 100 Phenyl-Hexyl from Dr. Maisch HPLC GmbH delivers advanced selectivity through the synergy of aromatic interaction and alkyl-chain retention – the ideal column for resolving complex, planar, and π-active analytes in modern HPLC.
