ReproSil-XR 120 NH2 from Dr. Maisch HPLC GmbH is a high-purity silica-based HPLC column with a 120 Å pore size and aminopropyl bonding. This polar stationary phase is ideal for carbohydrate separations, normal-phase chromatography, and HILIC (hydrophilic interaction chromatography) applications. The NH₂ functionality offers strong polar interactions and also enables weak anion-exchange behavior, providing versatile selectivity for a wide range of polar analytes.
ReproSil-XR 120 NH2 columns from Dr. Maisch HPLC GmbH deliver high-efficiency polar separations – the reliable choice for carbohydrate, HILIC, and normal-phase chromatography.
