ReproPak Phenyl

Aromatic HPLC Column for π–π Selectivity

ReproPak Phenyl is a silica-based HPLC column with a bonded phenyl stationary phase, designed to provide unique π–π interactions for improved separation of aromatic and conjugated analytes. Compared to conventional alkyl phases, the phenyl functionality offers complementary selectivity, making it particularly effective for structurally similar compounds containing aromatic rings. With its high-purity silica and durable bonding chemistry, ReproPak Phenyl delivers sharp peak shapes, reproducibility, and long column lifetimes under routine and demanding conditions. This makes it a versatile choice for pharmaceutical, biochemical, and environmental laboratories requiring aromatic selectivity.

ReproPak Phenyl combines aromatic selectivity with robust silica chemistry – the reliable choice for laboratories requiring π–π interaction in HPLC separations.

Key Features:

  • Silica-based stationary phase with phenyl bonded chemistry

  • π–π interactions for separation of aromatic and conjugated analytes

  • Complementary selectivity to standard C18 and C8 phases

  • Robust bonding ensures reproducibility and long column lifetime

  • Available particle size: 4 µm

Typical Applications:

  • Pharmaceutical separations of aromatic drugs and metabolites

  • Biochemical analysis of aromatic amino acids and conjugated biomolecules

  • Environmental monitoring of aromatic pollutants such as PAHs

  • Method development requiring orthogonal selectivity to alkyl phases
