The ratio of the total analytical concentration of a solute in the extract (regardless of its chemical form) to its total analytical concentration in the other phase. 1, record 1, English, - distribution%20ratio
Record number: 1, Textual support number: 1 OBS
In the past there has been much confusion between the "distribution ratio" as defined above, the value of which varies with experimental conditions, ... and the "true partition coefficient" which is by definition invariable or the "partition coefficient" or "distribution constant" which apply to a particular chemical species under specified conditions. For this reason the terms "distribution constant," "partition constant," "partition coefficient," "partition ratio" and "extraction constant" should not be used in this context. 1, record 1, English, - distribution%20ratio

Dans le passé, il y a eu beaucoup de confusion entre l'expression «rapport de distribution» tel que défini [ci-dessus], dont la valeur varie avec les conditions expérimentales [...] et le «coefficient de partage vrai» qui, par définition, est invariable ou avec le «coefficient de partage» ou la «constante de distribution» qui s'appliquent à une espèce chimique en particulier, dans des conditions données. Pour cette raison, les expressions «constante de distribution», «constante de partage», «coefficient de partage», «rapport de partage» et «constante d'extraction» ne devraient pas être utilisées dans ce contexte. 1, record 1, French, - rapport%20de%20distribution

Il est très rare qu'un solvant unique permette d'aboutir à des valeurs des facteurs de capacité convenables et surtout à une résolution optimale (on ne peut observer qu'une variation discontinue des facteurs de capacité et de la résolution lorsque l'on passe d'un solvant à un autre). C'est pourquoi on utilise très souvent des mélanges de solvants et plus particulièrement des mélanges binaires. 4, record 4, French, - coefficient%20de%20distribution%20massique
