Repromer is a polymer-based HPLC column series developed by Dr. Maisch HPLC GmbH, specifically designed for reversed-phase and ion-exchange chromatography under harsh chemical conditions. Built on cross-linked polymer particles, Repromer columns are free of silanol activity and offer exceptional stability across a wide pH range (typically pH 1–13), making them ideal for basic, strongly polar, or ionizable compounds that cannot be reliably analyzed on silica-based materials.
Available in various selectivities including reversed-phase (e.g. RP-1) and ion-exchange modes (e.g. IEX), Repromer supports long column lifetimes, even under aggressive mobile phases or elevated temperatures.
Repromer columns from Dr. Maisch HPLC GmbH offer durable, silanol-free chromatographic performance – the optimal choice for laboratories requiring chemically resistant HPLC columns for demanding applications.
