ReproSil 100 DNH is a spherical silica-based HPLC column with a diamine-bonded stationary phase, developed for anion exchange separations. The bonded diamine groups provide positively charged functionalities, enabling strong and selective retention of negatively charged analytes such as organic acids, nucleotides, and other anionic compounds. The robust diamine modification ensures reproducibility, sharp peak shapes, and long column lifetime. This makes ReproSil 100 DNH particularly suitable for biochemical, pharmaceutical, and environmental analyses involving acidic or anionic substances.
ReproSil 100 DNH combines the mechanical strength of spherical silica with strong diamine functionality – the reliable choice for efficient and reproducible anion exchange chromatography.
