Equisil BDS is a group of reversed-phase HPLC columns based on fully porous, high-purity silica, modified with classical alkyl phases such as C18 or C8 and enhanced through base deactivation (BDS). This surface treatment significantly reduces silanol interactions, leading to sharper peak shapes and greater reproducibility, especially for basic or polar compounds. Equisil BDS columns are ideal for routine reversed-phase analysis in pharmaceutical and general-purpose labs.
Equisil BDS columns offer stable and reproducible reversed-phase performance with enhanced peak shape – a reliable option for sensitive and basic compound analysis.
