ReproSil 100 CAT is a spherical silica-based HPLC column that has been specifically modified for cation exchange chromatography. The stationary phase carries a high density of negatively charged functional groups, enabling strong and selective retention of positively charged analytes such as amino acids, peptides, and basic pharmaceuticals. The optimized surface modification provides high reproducibility, sharp peak shapes, and robust stability, ensuring reliable performance in both routine and demanding analytical applications. With its strong cation exchange capacity, ReproSil 100 CAT is ideally suited for biochemical, pharmaceutical, and proteomics workflows.
ReproSil 100 CAT combines the mechanical stability of spherical silica with powerful cation exchange selectivity – the reliable choice for efficient and reproducible HPLC separations of basic analytes.
