Recent Advances in Bonded Phases for Liquid Chromatography

Chromatographic study on liquid‐phase adsorption on octadecylsilyl‐Silica Gel

“…It is estimated that about 70-80% of analytical separations have been carried out by using a reversed-phase technique. In the field of reversed-phase chromatography, octadecylsilyl silica gel (ODS) is used as a stationary phase in most cases (Bidlingmeyer, 1987;Krstulovic and Brown, 1982;Poole and Poole, 1991;Sander and Wise, 1987). Many kinds of techniques can be used in reversed-phase separation by modifying in mobile-phase conditions and bringing about extensive applications of reversed-phase liquid chromatography.…”

Solvent effect on adsorption phenomena in reversed‐phase liquid chromatography

“…In reversed-phase liquid chromatography with ODS, it is empirically known that aliphatic saturated compounds are adsorbed in preference to branch or aromatic unsaturated ones (Poole and Poole, 1991;Sander and Wise, 1987). In order to correlate adsorbability in reversed-phase mode with properties of adsorbates, several empirical parameters such as partition coefficient between n-octanol and water and solubility parameter have been proposed.…”

Adsorption characteristics of octadecylsilyl‐silica gel in gaseous systems

“…Reversed-phase mode, where octadecylsilyl-silica gel (ODS) is mainly used as a stationary phase, is extremely popular (Krstulovic and Brown, 1982;Sander and Wise, 1987;Poole and Poole, 1991). We reported earlier the study on liquid-phase adsorption of p-tert-octylphenol on the surface of ODS by the chromatographic method and the moment analysis (Miyabe and Suzuki, 1992).…”
