Exsil 80 SB-C8 is a silica-based HPLC stationary phase with an 80 Å pore size and a stable-bond octyl (C8) modification, designed for robust and reproducible reversed-phase separations of small molecules. The stable-bond (SB) technology provides enhanced chemical stability of the bonded phase, resulting in improved column lifetime and reliable performance under demanding chromatographic conditions.
The C8 alkyl chain offers moderate hydrophobic retention, enabling faster elution compared to C18 phases while maintaining good resolution and selectivity. Combined with the controlled pore structure and high surface area, Exsil 80 SB-C8 delivers sharp peak shapes, high efficiency, and excellent batch-to-batch reproducibility.
Exsil 80 SB-C8 provides balanced retention, enhanced stability, and reliable performance, making it a dependable choice for robust small-molecule reversed-phase HPLC separations.
