Ultrasep ES WAX FS

Weak Anion Exchange HPLC Column for Fast and Selective Separations

Ultrasep ES WAX FS is a silica-based HPLC column with weak anion exchange (WAX) functionality, optimized for fast and selective separations of negatively charged analytes. Its bonded amino groups provide controlled ionic interactions, enabling efficient retention and resolution of acidic and polar compounds while maintaining sharp peak shapes.

The FS design ensures faster analysis times and high reproducibility, making Ultrasep ES WAX FS particularly suitable for high-throughput laboratories in pharmaceuticals, biochemistry, and environmental testing. Its robust bonding chemistry delivers consistent performance and long column lifetimes under routine conditions.

Ultrasep ES WAX FS delivers fast, selective, and reproducible performance – the reliable choice for laboratories analyzing acidic and polar compounds with weak anion exchange chromatography.
