Ultrasep ES 100 NH₂ is a silica-based HPLC column with a 100 Å pore size and an aminopropyl (NH₂) bonded phase. This phase provides strong polar interactions and exhibits weak anion-exchange properties, making it highly versatile for applications such as carbohydrate analysis, HILIC (hydrophilic interaction chromatography), and normal-phase separations.
The column combines robust performance, high reproducibility, and excellent peak symmetry, ensuring reliable results in both method development and routine quality control.
Ultrasep ES 100 NH₂ delivers polar selectivity, reproducibility, and versatile chromatographic modes – the reliable choice for carbohydrate and polar compound separations in HPLC.
