ReproSil-Pur 120 NH2 is a silica-based HPLC column with bonded amino functionality on high-purity 120 Å silica. This polar stationary phase is ideally suited for carbohydrate analysis in normal-phase and HILIC modes, as well as for applications requiring selective interactions with polar analytes.
The amino bonding provides strong hydrogen bonding and dipole–dipole interactions, while the robust silica matrix ensures reproducibility, sharp peak shapes, and long column lifetimes. ReproSil-Pur 120 NH2 is a versatile tool for pharmaceutical, biochemical, food, and environmental laboratories.
ReproSil-Pur 120 NH2 combines robust amino chemistry with high-purity silica – the dependable choice for laboratories performing carbohydrate and polar compound analysis by HPLC.
