Title
(EN) DEVICE AND METHOD FOR MEASURING REACTIVE COMPONENTS IN GASES
(FR) DISPOSITIF ET PROCEDE DE MESURE DE COMPOSANTS REACTIFS DANS DES GAZ
Abstract
(EN)
A device and method is provided for measuring the amount of any reactive gaseous component in a single gas or in a mixture of two or more gases. The device comprises a reaction chambre, at least one means for supporting a removable catalyst suitable for catalysing the reaction between the reactive component and the gas or gases and at least one heat sensor for detecting and measuring the heat produced or absorbed by the reaction between any reactive component and one or more other gases. The supporting means is shaped to form a receptacle for holding the catalyst and the heat sensor so as to be capable of sensing the heat released or absorbed by any catalyst reaction, the arrangement being such that there is no chemical adherence between the heat sensor and the catalyst. The device us useful for detecting potentially explosive gas mixtures at low pressures.

L'invention se rapporte à un dispositif et à un procédé permettant de mesurer la quantité de n'importe quel composant gazeux réactif dans un gaz unique ou dans un mélange d'au moins deux gaz. Le dispositif comprend une chambre de réaction, au moins un moyen supportant un catalyseur amovible servant à catalyser la réaction entre le composant réactif et le ou les gaz, et au moins un détecteur de chaleur détectant et mesurant la chaleur produite ou absorbée par la réaction entre n'importe quel composant réactif et au moins un autre gaz. Le moyen de support est conçu de façon à former un réceptacle contenant le catalyseur et le détecteur de chaleur de façon à pouvoir détecter la chaleur libérée ou absorbée par toute réaction catalytique. Ce dispositif est conçu de façon à ce qu'il n'y ait pas d'adhérence chimique entre le détecteur de chaleur et le catalyseur. Le dispositif est utile pour détecter des mélanges gazeuz potentiellement explosifs à basses pressions.
