Abstract
L'invention concerne des appareils de chromatographie en phase gazeuse. Elle se rapporte à un appareil de chromatographie dans lequel la pression de sortie de la colonne mésuree au niveau d'un manomètre 66, est comprise entre 2 et 50 bars, si bien que l'analyse des constituants séparés peut être réalisée à la même vitesse que la séparation des constituants des échantillons. Application à l'identification des constituants de mélanges par chromatographie en phase gazeuse.
