Reprospher 200 C18-DE is a high-performance reversed-phase HPLC column from Dr. Maisch HPLC GmbH, packed with ultra-pure, fully porous spherical silica (200 Å pore size) bonded with octadecyl ligands and double endcapped to maximize deactivation of residual silanol groups. This advanced surface treatment ensures excellent peak symmetry, particularly for basic and polar analytes, and provides high reproducibility even under demanding conditions. The wide pore size makes this phase especially suitable for the analysis of larger biomolecules such as peptides, oligonucleotides, and other macromolecules, while the double endcapping enhances robustness and column lifetime.
Reprospher 200 C18-DE from Dr. Maisch HPLC GmbH delivers premium reversed-phase performance – the ideal choice for laboratories requiring excellent peak symmetry, high stability, and reliable separation of larger analytes.
