ReproSil Saphir 100 NH2 from Dr. Maisch HPLC GmbH is a high-purity silica-based HPLC column with a 100 Å pore size and an aminopropyl bonded phase. This polar stationary phase is ideal for carbohydrate separations, normal-phase chromatography, and HILIC (hydrophilic interaction chromatography) applications. The NH₂ functionality provides strong polar interactions while also allowing weak anion-exchange behavior, enabling versatile selectivity for polar analytes.
ReproSil Saphir 100 NH2 columns from Dr. Maisch HPLC GmbH deliver high-efficiency polar separations – the reliable choice for carbohydrate, HILIC, and normal-phase chromatography.
