[The method] was innovative in that it involved the concept of a stationary liquid (water) supported on an inert solid (silica), with the result that the solute molecules partitioned between the stationary liquid and a separate mobile liquid phase (chloroform). The technique came to be called partition chromatography.  2, record 1, English, - partition%20chromatography

The separation of a mixture occurs when a mobile phase(liquid or gas) passes over a stationary liquid phase which may be on paper, solid particles or the walls of a capillary tube. Partition processes include liquid-liquid, gas-liquid and paper chromatography.  3, record 1, English, - partition%20chromatography

La chromatographie de partage [...] a d'abord été utilisée pour la séparation des aminoacides [...] et a été depuis appliquée à des problèmes de séparation de différentes substances. La séparation est effectuée dans un nombre immense d'étapes de partage isolées, chacune de dimension microscopique dans une colonne (10 à 100 cm de longueur) remplie de grains d'une substance hydratée, insoluble et inerte, comme l'amidon ou le gel de silice. Les grains d'amidon ou de gel de silice sont hydrophiles et sont entourés par une phase d'eau finement liée, qui sert de phase stationnaire aqueuse à travers laquelle passe un flux de solvant non miscible qui traverse la colonne par gravité. Chaque grain d'amidon agit ainsi comme un séparateur microscopique.  4, record 1, French, - chromatographie%20de%20partage

The physical states of the mobile and stationary phases give rise to four basic types of chromatography :gas-liquid chromatography(GLC), gas-solid chromatography(GSC), liquid-liquid chromatography(LLC), and liquid-solid chromatography(LSC). Of the four basic types of chromatography, the two gas systems are independent and not subject to subdivisions. Thus the terms "gas-liquid chromatography" and "gas-solid chromatography" adequately identify the techniques involved. The liquid systems are not as easily described and are not mutually exclusive, which can lead to considerable confusion.  5, record 4, English, - gas%2Dsolid%20chromatography
