ReproSil 70 Diol

Small-Pore Diol Column for Normal-Phase and HILIC Small-Molecule Separations

ReproSil 70 Diol from Dr. Maisch HPLC GmbH is a fully porous, high-purity silica HPLC column with a 70 Å pore size and a diol-functionalized bonded phase. This stationary phase offers moderate polarity and hydrogen bonding capability, making it suitable for normal-phase chromatography and hydrophilic interaction chromatography (HILIC) of small molecules. The small pore size ensures a high surface area, providing sharp peaks, high efficiency, and excellent reproducibility for analytical applications in pharmaceutical, food, and chemical industries.

ReproSil 70 Diol columns from Dr. Maisch HPLC GmbH deliver versatile polar selectivity with high efficiency – the preferred choice for normal-phase and HILIC separations of small molecules.

Key Features:

  • Fully porous, ultra-pure silica with 70 Å pore size

  • Diol functional groups for controlled polar interactions

  • Suitable for normal-phase and HILIC applications

  • High efficiency for small-molecule separations

  • Manufactured and QC-tested by Dr. Maisch HPLC GmbH
