Adsorbosphere HS is a group of HPLC columns based on fully porous, high-purity silica with a higher specific surface area (HS = High Surface) compared to standard phases. The increased surface area allows for greater interaction between analytes and the stationary phase, resulting in stronger retention, higher resolution, and improved separation efficiency, independent of the bonded phase.
Available in both unmodified silica (Si) and reversed-phase chemistries like C18, Adsorbosphere HS columns offer robust performance for a wide range of analyte types and chromatographic conditions.
