ReproSil 300 SAX from Dr. Maisch HPLC GmbH is a fully porous, high-purity silica HPLC column with a 300 Å pore size and a strong anion exchange bonded phase based on quaternary ammonium functional groups. This phase provides strong ionic interactions for the retention and separation of negatively charged biomolecules, including proteins, nucleic acids, and glycoproteins. The wide-pore structure allows efficient mass transfer and accessibility for large biomolecules, ensuring high resolution, sharp peak shapes, and reproducible retention in both analytical and preparative workflows.
ReproSil 300 SAX columns from Dr. Maisch HPLC GmbH deliver robust and selective wide-pore anion exchange performance – the ideal choice for biomolecule chromatography in HPLC.
