Produced to ensure dependable processing results, the HPLC column Nucleodur® Polartec offers exceptional versatility within the realm of separation columns for HPLC. With its unique combination of high-purity Nucleodur® silica gel and a C18 modification featuring an embedded polar group, it exhibits both steric and enhanced polar selectivity. This hydrophobic phase boasts pronounced hydrophilic properties, making it particularly suitable for high aqueous conditions. Its separation mechanism is based on hydrophobic (van der Waals) and polar interactions, ensuring optimal performance for a wide range of applications such as amino acids, basic pharmaceuticals, nitrogen-containing compounds, organic acids, pesticides, phenols, water-soluble vitamins, and more. Additionally, its low bleeding characteristics make it ideal for LC/MS applications. Delivering
