Reprospher 100 C8-TN is a reversed-phase HPLC column from Dr. Maisch HPLC GmbH, packed with high-purity, fully porous spherical silica modified with trifunctionally bonded octyl groups and no endcapping (TN = trimodal, non-endcapped). This combination results in a stationary phase with moderate hydrophobic retention and increased silanol activity, enabling selective retention of polar and ionizable compounds through mixed-mode interactions. Ideal for analytical workflows that benefit from enhanced polar selectivity or controlled silanol interactions, Reprospher 100 C8-TN offers reliable performance in both isocratic and gradient reversed-phase separations.
Reprospher 100 C8-TN from Dr. Maisch HPLC GmbH offers distinct retention behavior and rugged reversed-phase performance – ideal for laboratories seeking alternative selectivity and enhanced polar interaction in HPLC.
