Ultrasep ES PEO is a silica-based HPLC column with a polyethylene oxide (PEO) bonded phase, engineered to enhance selectivity for strongly polar and hydrophilic compounds. The PEO functionality provides multiple hydrogen-bonding interaction sites, improving retention and resolution of analytes that are often difficult to separate on conventional alkyl phases.
This unique bonding chemistry minimizes peak tailing, ensures reproducibility, and offers long column lifetimes under routine use. Ultrasep ES PEO is particularly suitable for pharmaceutical, biochemical, and food analysis applications where polar analytes are of interest.
Ultrasep ES PEO combines strong polar selectivity with robustness – the reliable choice for laboratories analyzing hydrophilic and polar compounds in HPLC.
