A major difficulty with liquid chromatography is predicting the proper phase systems to use, and in most instances these must be determined experimentally. Both liquid-liquid (partition) and liquid-solid (adsorption) processes operate on differences in solute polarities since polarity is important in determining both adsorption and solubility. Liquid-liquid partition processes are quite sensitive to small molecular-weight differences in solutes and so are preferred for the separation of members of a homologous series.  2, fiche 1, Anglais, - liquid%2Dliquid%20partition

Selon le cas, on peut distinguer comme mécanismes fondamentaux : soit le partage entre deux phases liquides (on a alors une chromatographie de partage); soit la liaison de composés en mouvement avec la surface d'une phase stationnaire solide [...]  1, fiche 1, Français, - partage%20entre%20deux%20phases%20liquides
