Repromer

Polymer-Based HPLC Columns for Challenging and pH-Stable Separations

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.

Key Features:

• Cross-linked polymer stationary phase with no silanol interactions

• High chemical and pH stability (suitable for extreme pH conditions)

• Available in reversed-phase and ion-exchange versions

• Ideal for highly polar or ionizable analytes

• Manufactured by Dr. Maisch HPLC GmbH for robust long-term use

Typical Applications:

• Separation of basic drugs, polar compounds, and amines

• Ion-exchange chromatography under variable pH conditions

• Reversed-phase methods requiring non-aqueous solvents

• Quality control of complex formulations and excipients
