Reprospher 100 C8-NE

Non-Endcapped Octyl Column for Selectivity Toward Polar and Ionizable Compounds

Reprospher 100 C8-NE is a reversed-phase HPLC column from Dr. Maisch HPLC GmbH, featuring a non-endcapped octyl (C8) bonded phase on high-purity, fully porous silica with a 100 Å pore size. The absence of endcapping leaves residual silanol groups accessible, allowing enhanced polar interactions and ion-exchange effects. This makes Reprospher 100 C8-NE particularly valuable for method development and the separation of ionizable, basic, or highly polar analytes. Its unique selectivity profile provides an orthogonal alternative to standard endcapped reversed-phase columns, aiding in the resolution of closely related compounds and offering sharper insights during robustness studies.

Reprospher 100 C8-NE from Dr. Maisch HPLC GmbH offers distinct selectivity and enhanced polar interaction – ideal for advanced reversed-phase separations requiring fine-tuned control of silanol-mediated retention.

Key Features:

  • Octyl (C8) bonded reversed-phase phase without endcapping (NE)

  • Fully porous silica with 100 Å pore size

  • Increased silanol activity for polar interaction and alternative selectivity

  • Suitable for method development and retention tuning

  • Available in 5 µm

Typical Applications:

  • Separation of basic and ionizable analytes with enhanced silanol interaction

  • Resolution of isomeric or structurally similar compounds

  • Method scouting with orthogonal selectivity to endcapped C8/C18 columns

  • Retention tuning of polar compounds in reversed-phase HPLC
