Abstract
(EN)
This gas chromatograph system 10 comprises: a gas chromatograph 1; and a detector 2. The detector 2 includes an oxidation-reduction unit 14. The oxidation-reduction unit 14 includes an oxidation unit 146 and a reduction unit 147. The reduction unit 147 is provided downstream of the oxidation unit 146. The reduction unit 147 is disposed at a position other than a vertically upper side of the oxidation unit 146. Therefore, when air that has a high temperature around the oxidation unit 146 moves upward by convection, it is possible to suppress exposure of the reduction unit 147 to the high-temperature air.

L'invention concerne un système de chromatographe en phase gazeuse (10) comprenant : un chromatographe en phase gazeuse (1) ; et un détecteur (2). Le détecteur (2) comprend une unité d'oxydation-réduction (14). L'unité d'oxydation-réduction (14) comprend une unité d'oxydation (146) et une unité de réduction (147). L'unité de réduction (147) est située en aval de l'unité d'oxydation (146). L'unité de réduction (147) est située à une position autre qu'un côté verticalement supérieur de l'unité d'oxydation (146). Ainsi, lorsque de l'air présentant une température élevée autour de l'unité d'oxydation (146) se déplace vers le haut par convection, il est possible de supprimer l'exposition de l'unité de réduction (147) à l'air à haute température.

ガスクロマトグラフシステム10は、ガスクロマトグラフ1と検出器2とを備えている。検出器2は、酸化還元部14を備えている。酸化還元部14は、酸化部146と、還元部147とを備えている。還元部147は、酸化部146よりも下流側に設けられている。還元部147は、酸化部146に対して鉛直方向上方以外の位置に配置されている。そのため、酸化部146の周囲で高温となった空気が対流により上方に移動した場合に、還元部147がその高温の空気にさらされることを抑制できる。
