ReproSil BDS is a high-performance HPLC column group from Dr. Maisch HPLC GmbH, based on fully porous, high-purity silica with base-deactivated surface chemistry. The BDS (Base-Deactivated Silica) technology minimizes residual silanol interactions, providing excellent peak symmetry, reproducible retention times, and high efficiency — especially for basic and polar analytes.
Available in a variety of reversed-phase chemistries such as C18, C8, and phenyl, ReproSil BDS columns are suitable for routine analysis, method validation, and regulated pharmaceutical applications where precision and reproducibility are critical.
ReproSil BDS columns from Dr. Maisch HPLC GmbH deliver reliable, base-deactivated silica performance – the perfect choice for laboratories seeking high-quality, reproducible reversed-phase HPLC results.
