Abstract

Procédé et appareil pour analyser des mélanges de substances qui contiennent au moins un constituant soluble avec modification d'enthalpie. On injecte une quantité déterminée du mélange de substances dans un courant, s'écoulant uniformément, du solvant soumis à une régulation thermostatique constante, on mesure dans le solvant la variation maximale de température s'établissant, en considérant la direction d'écoulement du solvant, en arrière de la zone d'injection, et on compare cette valeur de mesure avec des variations maximales de températures mesurées auparavant. Application à l'analyse de mélanges de substances.
