Ultrasep ES 100 OH is a high-purity silica-based HPLC column with a 100 Å pore size and an unmodified silanol (OH) surface. Designed for normal-phase chromatography, the column offers strong polar interactions such as hydrogen bonding and dipole–dipole forces, delivering excellent selectivity for polar analytes and structural isomers.
With its high efficiency, reproducibility, and robust performance, Ultrasep ES 100 OH is an excellent choice for laboratories performing method development or specialized polar compound separations.
Ultrasep ES 100 OH delivers robust polar selectivity, reproducibility, and versatility – the reliable choice for normal-phase HPLC separations.
