ReproSil BDS C18 from Dr. Maisch HPLC GmbH is a fully porous, high-purity silica HPLC column a base-deactivated octadecyl bonded phase. The BDS (Base-Deactivated Silica) treatment minimizes residual silanol activity, delivering sharper peaks, reduced tailing, and reliable retention for basic, polar, and ionizable compounds. The 120 Å pore size provides excellent accessibility for small to medium-sized molecules, making this column a versatile choice for pharmaceutical, chemical, and environmental analysis.
ReproSil BDS C18 columns from Dr. Maisch HPLC GmbH deliver improved peak shapes and reproducibility – the ideal choice for high-quality reversed-phase HPLC of basic compounds.
