Abstract

La présente invention concerne un procédé d’analyse physico-chimique d’un échantillon gazeux comprenant un gaz porteur dans lequel est dilué du dichlore gazeux, le procédé d’analyse physico-chimique comprenant : a) une étape de conversion du dichlore de l’échantillon gazeux en dioxyde de chlore dans une ampoule de conversion ; b) une étape d’acquisition d’un spectre d’absorption de l’échantillon gazeux après exécution de l’étape a) dans une cellule de mesure reliée fluidiquement à l’ampoule de conversion ; c) une étape de traitement mathématique du spectre d’absorption en vue d’en déduire la concentration de dioxyde de chlore dans l’échantillon gazeux. Figure 1The present invention relates to a method for the physicochemical analysis of a gas sample comprising a carrier gas in which gaseous dichlorine is diluted, the physicochemical analysis method comprising: a) a step of converting the dichlorine of the gas sample into chlorine dioxide in a conversion bulb; b) a step of acquiring an absorption spectrum of the gas sample after performing step a) in a measuring cell fluidically connected to the conversion bulb; c) a step of mathematically processing the absorption spectrum in order to deduce therefrom the concentration of chlorine dioxide in the gas sample.
