ReproGel RP-1

Polymer-Based Reversed-Phase Columns for Stable and Silanol-Free HPLC

ReproGel RP-1 is a polymeric reversed-phase HPLC column series developed by Dr. Maisch HPLC GmbH, based on cross-linked polystyrene-divinylbenzene (PS-DVB) particles. These columns offer high chemical and pH stability and are completely free of silanol interactions, making them ideal for the separation of basic, polar, and ionizable compounds that often show poor peak shape on silica-based materials.

ReproGel RP-1 provides reproducible retention, robust peak symmetry, and long column lifetime, especially under aggressive conditions or when using non-aqueous mobile phases.

ReproGel RP-1 columns from Dr. Maisch HPLC GmbH offer high-performance polymer-based reversed-phase chromatography – ideal for challenging separations where silica-based columns reach their limits.
