Reprospher 100 DNH is an HPLC column from Dr. Maisch HPLC GmbH, packed with ultra-pure, fully porous spherical silica functionalized with diamine groups. This bonded phase provides weak anion exchange properties combined with polar interaction capability, making it ideal for the separation of acidic, polar, and hydrophilic analytes. The diamine functionality enables selective ionic interactions under appropriate pH and buffer conditions, while the silica substrate ensures mechanical stability and reproducible performance in both analytical and preparative workflows.
Reprospher 100 DNH from Dr. Maisch HPLC GmbH offers reliable weak anion exchange selectivity and polar interaction capability – ideal for laboratories requiring flexible separation modes for acidic and hydrophilic analytes.
