GromSil 120 Octyl-3 BA is a high-quality octyl bonded silica stationary phase designed for robust reversed-phase HPLC separations. Built on 120 Å pore size spherical silica, this phase provides balanced hydrophobic retention and excellent chromatographic efficiency for a wide range of pharmaceutical, environmental, and analytical applications.
The C8 functionalization offers moderate hydrophobic interaction, enabling efficient separations with shorter retention times compared to traditional C18 phases. This makes GromSil 120 Octyl-3 BA particularly suitable for compounds requiring controlled retention and fast elution without sacrificing resolution. The optimized bonding chemistry and high-purity silica matrix ensure excellent peak symmetry, reproducible retention behavior, and long column lifetime. The phase performs reliably under both gradient and isocratic conditions and is fully compatible with standard aqueous-organic mobile phases used in modern HPLC methods.
GromSil 120 Octyl-3 BA combines reliable C8 hydrophobic selectivity with high-purity silica technology—delivering reproducible, high-resolution reversed-phase separations for modern analytical laboratories.
