ReproSil 150 Si

Unmodified Silica with 150 Å Pore Size for Normal-Phase Chromatography

ReproSil 150 Si from Dr. Maisch HPLC GmbH is a fully porous, high-purity silica HPLC column with a 150 Å pore size and an unmodified silica surface. This stationary phase is ideal for normal-phase chromatography, adsorption chromatography, and SFC (supercritical fluid chromatography), particularly for medium-sized molecules, peptides, and small proteins. The larger pore size enhances mass transfer for biomolecules while maintaining the strong polar interaction properties of bare silica, ensuring consistent retention and excellent reproducibility.

ReproSil 150 Si columns from Dr. Maisch HPLC GmbH deliver reliable and reproducible normal-phase performance – the preferred choice for medium-sized molecule and peptide separations using bare silica.

Key Features:

  • Fully porous, ultra-pure silica with 150 Å pore size

  • Unmodified surface for strong polar interactions

  • Suitable for normal-phase and SFC applications

  • Optimized for peptides and medium-sized biomolecules

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

  • Available in 5 µm

Typical Applications:

  • Normal-phase separation of lipids and natural products

  • SFC analysis of biomolecules and chiral compounds

  • Adsorption chromatography of polar analytes

  • Method development requiring bare silica selectivity
