Equisil BDS C8

Base-Deactivated C8 Column for Balanced Retention and Improved Peak Shape

Equisil BDS C8 is a reversed-phase HPLC column based on fully porous, high-purity silica, bonded with octyl chains and treated with base deactivation (BDS) to reduce silanol activity. This results in better peak symmetry, especially for basic analytes, while offering moderate hydrophobic retention — making it ideal for faster analyses and compounds that are too strongly retained on C18 phases. Equisil BDS C8 delivers stable, reproducible performance and is suitable for routine reversed-phase applications in pharmaceutical, food, and general analytical laboratories.

Equisil BDS C8 offers improved peak shape and balanced retention – an ideal reversed-phase column for fast, reliable, and reproducible HPLC separations.
