A Modification on the Retention Equation of Liquid-Solid Chromatography lnk' = A + BlnC_(B_1)+CC_(B_1)

1 Theory Let us consider a liquid-solid adsorbent system. There are two solvents B_0 and B_1 in the liquid phase. B_0 is a weaker solvent and B_1 is a stronger one. By means of statistical thermodynamics and the ideal localized trap model, the adsorption equation of solvent B_0 on the surface of adsorbent phase can be expressed as follows.
