Equisil Gold C8 is a reversed-phase HPLC column based on ultra-high purity, fully porous silica, bonded with octyl groups and treated with advanced endcapping technology. Offering moderate hydrophobic retention and enhanced peak symmetry, this column is ideal for analytes that elute too slowly on C18 phases or for applications requiring shorter run times without compromising selectivity or reproducibility. Equisil Gold C8 is suited for use in regulated environments, pharmaceutical quality control, and method development, where precision and performance are critical.
Equisil Gold C8 provides high-performance reversed-phase separations with faster analysis times and excellent reproducibility – ideal for modern HPLC workflows.
