ReproSil-Pur Basic-C8-2

Optimized Medium-Chain Column for Robust Basic Compound Analysis

ReproSil-Pur Basic C8-2 is a silica-based HPLC column with octyl bonded chemistry on high-purity silica, specifically optimized for challenging basic analytes. Compared to standard C8 phases, the Basic C8-2 provides improved bonding technology and surface treatment, resulting in enhanced reproducibility, reduced silanol activity, and superior peak symmetry for amines, alkaloids, and other basic compounds.

The medium hydrophobic retention of the C8 bonding allows faster elution compared to C18 while still delivering strong separation performance. This makes ReproSil-Pur Basic C8-2 an excellent choice for routine pharmaceutical and biochemical analysis, as well as method development.

ReproSil-Pur Basic C8-2 provides optimized C8 retention with superior peak quality for basic analytes – the reliable choice for laboratories requiring robust and reproducible HPLC separations.

Key Features:

  • High-purity silica with octyl (C8) bonded chemistry

  • Enhanced surface treatment for optimized performance with basic analytes

  • Medium hydrophobic retention with shorter run times than C18 phases

  • Reduced silanol activity for sharp and symmetrical peak shapes

  • Available particle sizes: 3 µm, 5 µm

Typical Applications:

  • Pharmaceutical analysis of basic drugs, alkaloids, and amines

  • Biochemical separations of polar and moderately hydrophobic metabolites

  • Food and beverage analysis of nitrogen-containing compounds

  • Environmental testing of cationic and polar organic pollutants

  • Method development requiring reproducibility and orthogonal selectivity
