Abstract:
(EN) This three-component simultaneous analysis device is a device for detecting three components, comprising methane gas, carbon dioxide and nitrous oxide, contained in atmospheric gas, which is an assay sample. The three-component simultaneous analysis device includes: a first gas flow passage (A); a second gas flow passage (B) and a third gas flow passage (C) located downstream of the first gas flow passage (A); and a switching valve (400) which is located between the first gas flow passage (A) and the second gas flow passage (B) and between the first gas flow passage (A) and the third gas flow passage (C), and which is used to switch between a first state in which the first gas flow passage (A) and the second gas flow passage (B) communicate with one another, and a second state in which the first gas flow passage (A) and the third gas flow passage (C) communicate with one another. The first gas flow passage (A) includes a first column (60) disposed in order to obtain a first gas phase including methane gas, and a second gas phase including carbon dioxide and nitrous oxide. The second gas flow passage (B) includes a hydrogen flame ionization detector (100). The third gas flow passage (C) includes: a second column (70) comprising a packed column; a third column (80) which is downstream of the second column (70), comprises a capillary column or a stainless steel column, and is disposed in order to obtain a third gas phase including carbon dioxide and a fourth gas phase including nitrous oxide; a thermal conductivity detector (200); and an electron capture detector (300).
(FR) L'invention concerne un dispositif d'analyse simultanée de trois composés qui est un dispositif de détection de trois composés, comprenant du méthane gazeux, du dioxyde de carbone et de l'oxyde nitreux, contenus dans un gaz atmosphérique, qui est un échantillon de dosage. Le dispositif d'analyse simultanée de trois composés comprend : un premier passage d'écoulement de gaz (A) ; un deuxième passage d'écoulement de gaz (B) et un troisième passage d'écoulement de gaz (C) situés en aval du premier passage d'écoulement de gaz (A) ; et une vanne de commutation (400) qui est située entre le premier passage d'écoulement de gaz (A) et le deuxième passage d'écoulement de gaz (B) et entre le premier passage d'écoulement de gaz (A) et le troisième passage d'écoulement de gaz (C), et qui est utilisée pour commuter entre un premier état dans lequel le premier passage d'écoulement de gaz (A) et le deuxième passage d'écoulement de gaz (B) communiquent l'un avec l'autre, et un second état dans lequel le premier passage d'écoulement de gaz (A) et le troisième passage d'écoulement de gaz (C) communiquent l'un avec l'autre. Le premier passage d'écoulement de gaz (A) comprend une première colonne (60) disposée afin d'obtenir une première phase gazeuse comprenant du méthane gazeux, et une deuxième phase gazeuse comprenant du dioxyde de carbone et de l'oxyde nitreux. Le deuxième passage d'écoulement de gaz (B) comprend un détecteur à ionisation de flamme d'hydrogène (100). Le troisième passage d'écoulement de gaz (C) comprend : une deuxième colonne (70) comprenant une colonne garnie ; une troisième colonne (80) qui est en aval de la deuxième colonne (70), qui comprend une colonne capillaire ou une colonne en acier inoxydable, et qui est disposée afin d'obtenir une troisième phase gazeuse comprenant du dioxyde de carbone et une quatrième phase gazeuse comprenant de l'oxyde nitreux ; un détecteur de conductivité thermique (200) ; et un détecteur à capture d'électrons (300).
