Ultrasep ES AZO

Azo-Bonded HPLC Column for Polar and Specialty Applications

Ultrasep ES AZO is a silica-based HPLC column featuring an azo-bonded stationary phase, designed to provide unique selectivity for polar and aromatic compounds. The azo functionality introduces specific interaction mechanisms, enabling efficient retention and separation of challenging analytes that are difficult to resolve with conventional reversed-phase or amino columns.

This distinctive surface chemistry supports reproducible separations with sharp peak shapes, while the robust bonding ensures long column lifetime and consistent performance even under demanding analytical conditions. Ultrasep ES AZO is particularly suited for method development when orthogonal selectivity is required.

Ultrasep ES AZO offers unique azo-based selectivity combined with robustness and reproducibility – the ideal choice for advanced HPLC separations where conventional phases are not sufficient.

Key Features:

  • Silica-based stationary phase with azo-bonded chemistry

  • Unique selectivity for polar and aromatic analytes

  • Enhanced resolution for challenging compound classes

  • Robust bonding for high reproducibility and extended lifetime
