Exsil 80 ODS is a silica-based HPLC stationary phase with an 80 Å pore size and an octadecyl (C18, ODS) bonded surface, designed for high-efficiency reversed-phase separations of small molecules. The controlled pore structure provides a high surface area, enabling strong hydrophobic interactions, sharp peak shapes, and reproducible retention behavior.
The ODS modification delivers strong hydrophobic retention and broad applicability, making Exsil 80 ODS suitable for both routine analytical HPLC and method development. It is particularly effective for compounds that require stronger retention than C8 or other medium-chain phases.
Exsil 80 ODS provides strong hydrophobic retention, high efficiency, and reliable reproducibility, making it a dependable choice for small-molecule reversed-phase HPLC separations.
