Exsil 80 ODS-1 is a silica-based HPLC stationary phase with an 80 Å pore size and an octadecyl (C18, ODS-1) bonded surface engineered for controlled hydrophobic retention in reversed-phase HPLC. Compared to high-carbon-load C18 phases, ODS-1 provides moderate retention strength, enabling improved selectivity and shorter analysis times for small molecules.
The optimized surface coverage and high surface area support sharp peak shapes, high chromatographic efficiency, and reproducible retention behavior, making Exsil 80 ODS-1 suitable for both routine analysis and method development.
Exsil 80 ODS-1 delivers balanced hydrophobic retention, high efficiency, and reliable reproducibility, making it an effective solution for controlled reversed-phase HPLC separations of small molecules.
