Ultrasep ES Chair

Specialty HPLC Column for Structural and Conformational Selectivity

Ultrasep ES Chair is a silica-based HPLC column with a unique bonded phase designed to provide enhanced conformational and structural selectivity. Its innovative surface chemistry enables improved separation of compounds with subtle structural differences, such as stereoisomers, conformers, and complex organic molecules.

The Chair phase combines hydrophobic and steric interaction mechanisms, allowing for sharper peaks and superior resolution where conventional alkyl or aromatic phases may fail. With robust bonding chemistry, the column ensures reproducibility and long operational lifetime, making it ideal for demanding applications in pharmaceuticals, natural products, and advanced chemical research.

Ultrasep ES Chair offers a unique approach to structural and conformational separations – the reliable choice for challenging HPLC applications requiring advanced selectivity.
