The present invention is an improvement to two-dimensional comprehensive gas chromatography. The improvement is a two-valve switching modulator connecting two different type of separation columns. The advantages of current invention are (1) a simple system can be built by readily available parts; (2) no specific materials required (other than electricity) to operate the system, especially, do not need any type of coolant; (3) can be build on any GC as an externally added on unit; (4) The first and the second dimensional column flow are independently controlled, it is easier to design the experiment; and (5) it is cost effective, the cost of building this system is inexpensive than other type of modulation.
Cette invention concerne une amélioration touchant la chromatographie en phase gazeuse bidimensionnelle globale. L'amélioration concerne un modulateur de commutation à deux valves reliant deux types différents de colonne de séparation. L'invention offre les avantages suivants: (1) système simple réalisable avec des pièces facilement disponibles; (2) pas de matériaux spécifiques requis (autres que de l'électricité) pour l'utilisation du système et, spécifiquement, aucun type de réfrigérant requis; (3) possibilité de réalisation sur n'importe quelle installation en phase gazeuse en tant qu'unité extérieure rapportée; (4)commande indépendante des premier et second flux de colonne dimensionnelle, ce qui facilite la conception de l'expérience; et (5) bon rapport coût-efficacité, le coût de réalisation de ce système étant plus faible que pour des systèmes d'autre type.
