Title: | Effect of the mobile phase on solute retention in liquid-solid chromatography | Authors: | Petrovic S. Spika M. |
Issue Date: | 1-Jan-1991 | Journal: | Journal of Liquid Chromatography | Abstract: | Utilizing retention data estimated by HPTLC on silica and activity coefficients in the non-aqueous mobile phase determined on the basis of saturation solubility of solutes, the effect of the mobile phase on retention of a set of structurally different solutes was studied. A quadratic relationship between the logarithm of retention factors or activity coefficients and the volume fraction of ethyl acetate in heptane-ethyl acetate solution was observed, suggesting a common retention mechanism in liquid chromatography. The retention and/or relative retention of a solute was affected by both the mobile and the stationary phase. The magnitude of these effects depended merely on the molecular structure of a solute. | URI: | https://open.uns.ac.rs/handle/123456789/12423 | ISSN: | 01483919 | DOI: | 10.1080/01483919108049376 |
