Abstract
The method suggested for characterization of selectivity, based on an adequate calibration homologous series, is used for predictions of relative retentions of various solutes. It allows the prediction of possible changes in the order of elution with changing composition of mobile phase (selectivity cross-overs) from the combination of constants characterizing lipophilic and polar contributions to selectivity. It also allows the characterization and prediction of selectivity in ternary mobile phases containing two different organic solvents and water. Using this method, it is possible to predict the retention on one column from the constants that characterize the lipophilicites and polarities of the functional groups of the solutes measured on an- other column (with bonded alkyl chains of the same length) with a probable relative error between 10 and 20%.
