Ultrasep ES Amid RP18AE is a silica-based HPLC column with a polar-embedded amidic C18 bonded phase and endcapping. The embedded amide group provides enhanced polar selectivity and improves peak symmetry for basic analytes, while the endcapping reduces residual silanol activity, ensuring high reproducibility and sharp peaks.
This combination of polar and hydrophobic retention makes the column ideal for complex mixtures, stability-indicating assays, and pharmaceutical analysis, where robust performance under harsh pH and temperature conditions is required.
Ultrasep ES Amid RP18AE delivers enhanced polar selectivity, minimized silanol interactions, and robust performance – the reliable choice for challenging reversed-phase HPLC separations.
