Abstract[English]
Disclosure herein is Thermal Conductivity Detector (TCD) based Gas Chromatography (GC) device (100, 200). The TCD based GC device (100, 200) comprises; TCD oven (102, 202) formed by plurality of walls, wherein TCD oven (102, 202) comprises inlet valve (106, 206) and one outlet valve (108, 208); TCD element (112, 212) housed in the TCD oven (102, 202); heating source (110, 210) mounted on any one of the plurality of walls of the TCD oven (102, 202); Thermoelectric Generator (TEG) (114, 214) thermally connected to TCD element (112, 212); and detector circuit (300) configured to: determine thermal gradient in mixture gas, wherein the mixture gas is mixture gas of carrier gas and analyte gas fed to TCD oven (102, 202); and generate electrical signal based on thermal gradient. The TCD based GC device (100, 200) provides enhanced ability to increase the accuracy of GC analysis.[French]
L'invention concerne un dispositif de chromatographie en phase gazeuse (GC) à détecteur de conductivité thermique (TCD) (100, 200). Le dispositif de GC à TCD (100, 200) comprend : un four de TCD (102, 202) formé par une pluralité de parois, le four de TCD (102, 202) comprenant une soupape d'entrée (106, 206) et une soupape de sortie (108, 208) ; un élément TCD (112, 212) logé dans le four de TCD (102, 202) ; une source de chauffage (110, 210) montée sur l'une quelconque de la pluralité de parois du four de TCD (102, 202) ; un générateur thermoélectrique (TEG) (114, 214) relié thermiquement à l'élément TCD (112, 212) ; et un circuit détecteur (300) configuré pour : déterminer un gradient thermique dans un gaz de mélange, le gaz de mélange étant un gaz de mélange de gaz vecteur et de gaz d'analyte introduit dans un four de TCD (102, 202) ; et générer un signal électrique sur la base d'un gradient thermique. Le dispositif de GC à TCD (100, 200) offre une capacité améliorée à augmenter la précision de l'analyse GC.
