ReproSil BDS C18

Base-Deactivated C18 Column for Improved Peak Shape of Basic Analytes

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.

Key Features:

  • Fully porous, ultra-pure silica with 120 Å pore size

  • Base-deactivated C18 bonding – USP L1 classification

  • Excellent peak symmetry for basic and polar analytes

  • High efficiency and reproducibility under gradient and isocratic conditions

  • Manufactured and QC-tested by Dr. Maisch HPLC GmbH
