Equisil BDS C18 is a reversed-phase HPLC column based on fully porous, high-purity silica, bonded with octadecyl chains and treated with base deactivation (BDS) to minimize silanol interactions. This enhances peak shape, especially for basic and polar analytes, and improves reproducibility in routine reversed-phase workflows. Equisil BDS C18 is ideal for pharmaceutical QC, impurity profiling, and general-purpose reversed-phase separations.
Equisil BDS C18 provides enhanced selectivity and peak shape for sensitive reversed-phase analyses – a dependable column for high-quality HPLC workflows.
