Abstract

L'invention concerne un procédé et un dispositif d'injection de l'échantillon dans la colonne de séparation d'un chromatographe en phase gazeuse. Selon le procédé: (a) on relie les moyens d'alimentation (7) d'échantillon à la colonne (12) par, d'amont en aval: un moyen d'injection (2), une chambre d'expansion (3), un moyen de connexion (4) pourvu d'une entrée (13) pour le gaz vecteur; (b) on alimente le gaz vecteur par l'entrée (13) du moyen de connexion (4); (c) on injecte l'échantillon par le moyen d'injection (2); (d) après un temps prédéterminé on arrête l'alimentation de gaz vecteur selon (b); (e) on alimente pendant un temps prédéterminé du gaz vecteur par le moyen d'injection (2); (f) on arrête l'alimentation du gaz vecteur selon (e); (g) on alimente le gaz vecteur par l'entrée (13) du moyen de connexion (4), le moyen d'injection (2) étant relié à des moyens de fuite (17). Le procédé et le dispositif sont destinés à l'analyse industrielle en ligne.
