ReproSil 70 Si from Dr. Maisch HPLC GmbH is a fully porous, high-purity silica HPLC column with a 70 Å pore size and an unmodified silica surface. This phase is ideal for normal-phase chromatography, adsorption chromatography, and SFC (supercritical fluid chromatography) of small molecules, offering strong polar interactions and excellent separation efficiency. The small pore size provides a high surface area, ensuring sharp peak shapes, high resolution, and consistent retention for routine and method development applications.
ReproSil 70 Si columns from Dr. Maisch HPLC GmbH deliver high-efficiency polar interaction separations – the preferred choice for small-molecule chromatography in normal-phase and SFC applications.
