Eluotropic series solvent classification

Thus, stronger adsorption of the mobile phase decreases adsorption of the solute. Solvents can be classed according to their strength of adsorption. Such a quantitative classification is referred to as an eluotropic series. Table 21.3 is an abbreviated eluo-tropic series specifically for alumina as the adsorbent, but qualitatively this series holds for other polar adsorbents as well [4]. [Pg.657]

A classification of solvents to their ability to adsorb on the stationary phase is called an eluotropic series (Table III). Retention of solute is reduced with mobile phase solvents of higher solvent strength parameter, . Solvent polarity parameters ((f)) are similar to e values. They can be used to estimate the overall polarity of a binary solvent as = ( a PX + Pg For example, (p values for... [Pg.220]
