ReproSil-XR 300 SCX from Dr. Maisch HPLC GmbH is a high-purity silica-based wide-pore HPLC column with a 300 Å pore size and a strong cation exchange (SCX) bonded phase based on sulfonic acid functional groups. This stationary phase provides strong ionic retention for positively charged biomolecules, ensuring high resolution, sharp peak shapes, and excellent reproducibility. The wide-pore structure allows optimal accessibility and efficient mass transfer for high-molecular-weight analytes such as proteins, enzymes, and peptides, making it particularly suited for proteomics and biopharmaceutical applications.
ReproSil-XR 300 SCX columns from Dr. Maisch HPLC GmbH combine wide-pore accessibility with strong ionic selectivity – the optimal choice for high-resolution large biomolecule chromatography.
