ReproPak C8

Medium Hydrophobicity HPLC Column for Routine and Robust Separations

ReproPak C8 is a silica-based HPLC column with an octyl bonded phase, designed to deliver balanced hydrophobic retention and faster elution compared to C18 phases. Its medium-chain alkyl bonding makes it suitable for moderately hydrophobic analytes while offering complementary selectivity for method development. Built on high-purity silica with durable bonding chemistry, ReproPak C8 ensures sharp peak shapes, reproducibility, and long column lifetimes. This makes it an excellent choice for routine pharmaceutical, biochemical, food, and environmental analyses.

ReproPak C8 provides balanced hydrophobic retention with robust reproducibility – the reliable choice for laboratories performing routine HPLC separations.

Key Features:

  • Silica-based stationary phase with octyl (C8) bonded chemistry

  • Medium hydrophobic retention with faster elution than C18

  • Robust bonding ensures reproducibility and durability

  • High reproducibility with sharp peak shapes

  • Available particle size: 4 µm

Typical Applications:

  • Pharmaceutical impurity profiling and stability assays

  • Biochemical separations of moderately hydrophobic drugs and metabolites

  • Food and beverage analysis of additives, preservatives, and contaminants

  • Environmental monitoring of organic pollutants

  • Method development requiring complementary selectivity to C18
