ReproSil 70 NH2

Small-Pore Amino Column for Carbohydrate and Polar Compound Analysis

ReproSil 70 NH2 from Dr. Maisch HPLC GmbH is a fully porous, high-purity silica HPLC column with a 70 Å pore size and an aminopropyl bonded phase. This polar stationary phase is ideal for carbohydrate analysis, sugar alcohol separations, and polar compound chromatography in both normal-phase and HILIC modes. The small pore size provides a high surface area, delivering sharp peak shapes, excellent reproducibility, and high separation efficiency for small molecules.

ReproSil 70 NH2 columns from Dr. Maisch HPLC GmbH deliver reliable, high-efficiency polar separations – the preferred choice for carbohydrate and HILIC applications in small-molecule HPLC.
