Exsil 80 SB-C18 is a silica-based HPLC stationary phase with an 80 Å pore size and a stable-bond octadecyl (C18) modification, developed for robust and reproducible reversed-phase separations of small molecules. The stable-bond (SB) technology enhances the chemical stability of the bonded phase, providing extended column lifetime and reliable performance under demanding chromatographic conditions.
The C18 alkyl chains deliver strong hydrophobic retention and broad applicability, while the controlled pore structure and high surface area support high chromatographic efficiency, sharp peak shapes, and consistent retention behavior. Exsil 80 SB-C18 is suitable for both routine analytical HPLC and method development where robustness and reproducibility are critical.
Exsil 80 SB-C18 delivers strong hydrophobic retention, enhanced stability, and reliable performance, making it a dependable choice for robust small-molecule reversed-phase HPLC separations.
