This device comprises a means (111) for forming a gaseous flow from the sample, and a means (121) for separation by means of selective retention each gaseous constituent. It comprises a means (113) for combustion of the gaseous flow in order to form a gaseous residue from each constituent, and a means (115) for quantifying the content of each constituent to be analysed in the gaseous flow. The quantification means (115) comprise an optical measurement cell (127) which is connected to the combustion means (113), and a means (161) for introducing a laser incident optical signal into the cell (127). The quantification means (115) also comprise means (133) for measuring a transmitted optical signal resulting from an interaction between the optical signal and each gaseous residue in the cell (127), and means (125) for calculating said content on the basis of the transmitted optical signal.
L'invention concerne un dispositif comprenant un moyen (111) pour former un flux gazeux à partir d'un échantillon, ainsi qu'un moyen (121) pour séparer chaque constituant gazeux par rétention sélective. Ce dispositif comprend également un moyen (113) pour la combustion du flux gazeux en vue de former un résidu gazeux à partir de chaque constituant et un moyen (115) pour quantifier la concentration de chaque constituant à analyser dans le flux gazeux. Le moyen de quantification (115) comprend une cellule de mesure optique (127) qui est reliée au moyen de combustion (113), ainsi qu'un moyen (161) pour introduire un signal optique incident laser dans la cellule (127). Le moyen de quantification (115) comprend également un moyen (133) pour mesurer un signal optique transmis résultant d'une interaction entre le signal optique et chaque résidu gazeux dans la cellule (127), ainsi qu'un moyen (125) pour calculer ladite concentration d'après le signal optique transmis.
