ReproSil-XR 120 NH2-e from Dr. Maisch HPLC GmbH is a high-purity silica-based HPLC column with a 120 Å pore size and endcapped aminopropyl (NH₂) bonding. The endcapping process reduces residual silanol activity, improving peak symmetry and reproducibility while maintaining strong polar interaction capability. This column is well-suited for carbohydrate analysis, HILIC (hydrophilic interaction chromatography), and normal-phase applications, offering enhanced robustness for demanding analytical workflows.
ReproSil-XR 120 NH2-e columns from Dr. Maisch HPLC GmbH combine polar interaction selectivity with improved chromatographic performance – the optimal choice for high-precision polar compound separations.
