Ultrasep ES Pharm-Spezial RP18e is a silica-based HPLC column with an endcapped specialty C18 bonded phase, engineered to combine strong hydrophobic retention with minimized silanol activity. The advanced endcapping process reduces secondary interactions, ensuring sharper peak shapes and higher reproducibility, especially for basic and polar compounds.
The “Spezial” bonding chemistry enhances robustness and long-term stability, making this column suitable for demanding pharmaceutical applications such as impurity profiling, stability-indicating assays, and regulatory testing. With particle size options of 5 µm and 7 µm, Pharm-Spezial RP18e provides flexibility for both routine quality control and advanced analytical workflows.
Ultrasep ES Pharm-Spezial RP18e combines the benefits of endcapping and specialty C18 bonding – the reliable choice for pharmaceutical laboratories requiring reproducible and long-lasting HPLC separations.
