Ultrasep ESD Chol is a silica-based HPLC column with a cholesterol-bonded stationary phase, designed to provide enhanced shape selectivity for structurally similar compounds. The bulky cholesterol groups create a unique steric environment that enables effective separation of isomers, sterols, and other closely related analytes.
This distinctive chemistry combines hydrophobic retention with steric interaction mechanisms, delivering sharp peak shapes, reproducibility, and robustness under routine and demanding analytical conditions. Ultrasep ESD Chol is particularly suitable for pharmaceutical, biochemical, and food applications requiring advanced selectivity.
Ultrasep ESD Chol delivers robust shape selectivity and reproducibility – the reliable choice for laboratories analyzing sterols, lipids, and other closely related compounds.
