Grom Sapphire 65 C8 is a silica-based HPLC column with an octyl (C8) bonded phase, built on high-purity 65 Å silica. Compared to C18 phases, the shorter C8 chains provide reduced hydrophobic retention, enabling faster elution and improved peak resolution for moderately hydrophobic analytes.
With its optimized surface chemistry, Sapphire 65 C8 ensures reproducible performance, sharp peak shapes, and long column lifetimes. It is particularly suitable for pharmaceutical quality control, biochemical analysis, and routine testing of complex mixtures where balanced hydrophobicity is required.
Grom Sapphire 65 C8 provides reliable performance and balanced hydrophobic selectivity – the dependable choice for laboratories requiring efficient small-molecule separations in HPLC.
