Summary

The influence of the mutual solubility of the stationary and the mobile phases in connection with the determination of activity coefficients by liquid-liquid chromatography is considered. An equation is proposed and verified for the retention of solutes in liquid-liquid chromatography using squalane as the stationary phase and acetonitrile or aniline as the mobile phase.

Résumé

On étudie l'influence de la solubilité mutuelle de la phase fixe et de la phase mobile dans la détemination des coefficients d'activité par chromatographie liquide-liquide. On propose et vérifie une équation qui pemet d'exprimer la rétention des solutés en chromatographie liquide-liquide en fonction des coefficients d'activité dans le cas où le squalane est utilisé comme phase fixe et l'aniline et l'acétonitrile comme phases mobiles.
