ReproSil 100 XBD is a fully porous, high-purity silica HPLC column group from Dr. Maisch HPLC GmbH, featuring 100 Å pore size and base-deactivated surface chemistry for superior performance with basic and polar analytes. The XBD (eXtra Base-Deactivated) modification reduces residual silanol activity, resulting in sharper peaks, minimal tailing, and improved reproducibility, even for compounds prone to secondary interactions on conventional silica.
Available with popular bonded phases such as C18 and C8, ReproSil 100 XBD columns combine strong hydrophobic retention with excellent selectivity for a broad analyte range.
ReproSil 100 XBD columns from Dr. Maisch HPLC GmbH deliver optimized reversed-phase performance – the ideal choice for laboratories needing base-deactivated silica to achieve high-quality chromatographic results.
