Abstract
Injecteur à vaporisation pour colonnes de chromatographies en phase gazeuse, du type comprenant une chambre de vaporisation fermée et chauffée alimentée avec le vecteur et avec la substance à analyser injectée au moyen de l'aiguille d'une seringue d'injection qui peut être introduite à travers un conduit débouchant dans la chambre même, caractérisé en ce que le conduit d'insertion de l'aiguille est fermé par une soupape 44 ayant au moins deux positions, qui peut être actionnée pour ouvnr le conduit pour l'insertion de l'aiguille, et en ce que l'on crée un gradient de pression dans une partie du parcours d'insertion de l'aiguille jusqu'à la chambre de vaporisation 24. Application : chromatographie en phase gazeuse.
