Ultrasep ES C30-DM is a silica-based HPLC column with a long-chain C30 bonded phase, designed to deliver superior shape selectivity and high-resolution separations. The extended alkyl chains provide enhanced steric interaction, making this column particularly effective for the separation of structural isomers, geometric isomers, and complex mixtures of closely related compounds.
Compared to conventional C18 phases, Ultrasep ES C30-DM offers stronger shape discrimination and improved peak resolution, making it an excellent choice for challenging pharmaceutical, food, and natural product analyses. The DM bonding chemistry ensures high stability, reproducibility, and long lifetime under routine use.
Ultrasep ES C30-DM delivers unmatched shape selectivity and reproducibility – the reliable choice for laboratories requiring precise separation of isomers and structurally related compounds.
