ReproSil Star NH2 is a silica-based HPLC column with an aminopropyl bonded phase, designed for pharmaceutical, biotechnical, and carbohydrate separations. The polar amino functionality enables multiple interaction mechanisms, including normal-phase, weak anion exchange, and hydrogen bonding, offering exceptional versatility for polar and hydrophilic analytes.
The high-purity silica used in the ReproSil Star series ensures excellent mechanical stability, reproducibility, and long column lifetime. ReproSil Star NH2 provides sharp peak shapes, stable retention, and consistent performance even under varying mobile phase conditions, making it ideal for both routine and advanced chromatographic applications.
ReproSil Star NH2 combines polar selectivity with the stability of high-purity silica – the reliable choice for versatile and reproducible HPLC separations in pharmaceutical and biotechnical laboratories.
