    Empirical multiparameter relationships between retention indices and physicochemical properties of alkylbenzenes (1983)
    Springer
    Chromatographia 17 (1983), S. 664-668

    ISSN: 1612-1112
    Keywords: Gas Chromatography ; Retention Index ; Alkylbenzenes ; Physicochemical properties ; Multiparameter equations

    Topics: Chemistry and Pharmacology
    Notes: Summary On the basis that relationships between chromatographic retention parameters and the boiling points of the solutes are suitable for calculating retention indices in the absence of solute-stationary phase interactions, the use of several physicochemical properties of the solutes to account for the non-specific solutephase interactions according to the “dielectric approach” theory of non-specific solvation, is tested. Equations with two or more parameters, in which one of them is always the boiling point, are adjusted by the least-squares method, and their applicability to the calculation of the retention indices of the alkylbenzenes on stationary phases of different polarity is discussed on the basis of the correlation statistics.

    Prediction of gas chromatographic retention indices of linear, branched, and cyclic alkanes from their physicochemical properties (1984)
    Weinheim : Wiley-Blackwell
    Journal of High Resolution Chromatography 7 (1984), S. 191-195 
    Details
    ISSN: 0935-6304
    Keywords: Gas chromatography ; Saturated hydrocarbons ; Retention indices ; Molar refraction ; Chemistry ; Analytical Chemistry and Spectroscopy

    Topics: Chemistry and Pharmacology
    Notes: Kováts retention indices for a series of linear, branched, and cyclic alkanes on squalane at any temperature, and on other stationary phases of different polarity at a given temperature, are related to physicochemical properties of the solutes, such as boiling point and molar refraction, by multiple regression analysis. The equations found permit calculation of the Kováts retention index for all alkanes, with standard deviations close to experimental error. The same equations can also be used for calculating the physicochemical parameters they contain.
