ReproSil BDS C8 from Dr. Maisch HPLC GmbH is a fully porous, high-purity silica HPLC column with a base-deactivated octyl bonded phase. The BDS (Base-Deactivated Silica) surface treatment significantly reduces residual silanol activity, ensuring sharper peaks, less tailing, and consistent retention for basic, polar, and ionizable analytes. With its moderate hydrophobic retention, ReproSil BDS C8 is ideal for compounds requiring shorter run times and faster equilibration compared to C18 phases, while still offering excellent selectivity and resolution.
ReproSil BDS C8 columns from Dr. Maisch HPLC GmbH combine balanced retention with improved peak shape – the versatile choice for high-performance reversed-phase HPLC.
