Title (EN) MULTIFUNCTIONAL DETECTOR FOR GASEOUS COMPOUNDS, AND USES THEREOF
(FR) DÉTECTEUR MULTIFONCTIONNEL DE COMPOSÉS GAZEUX ET SES APPLICATIONS
Abstract:
(EN) The invention relates to a multifunctional detector for gaseous compounds, or mixtures of gaseous compounds, selected from NH2Cl, NHCl2, NCl3, total chlorine, NOx, where x=1 or 2, O3, and X2, where X=Cl, Br, or I, in a sample, said detector including a first sensor including an iodide and a reactive compound selected from starch, amylose, amylopectin, xyloglucan, xylan, chitosan, glycogen, polyvinyl alcohol, cellulose or a cellulose compound, α-cyclodextrin, theobromine, and polypropylene block polymers and polyethylene oxide block polymers, included in a block of sol-gel material that is absorbent in the UV spectrum but not in the visible spectrum. The invention also relates to the uses of said detector.
(FR) Détecteur multifonctionnel de composés gazeux ou mélanges de composés gazeux choisis parmi NH2Cl, NHCl2, NCl3, chlore total, NOx où x=1 ou 2, O3 et X2 où X=Cl, Br ou I dans un échantillon, ledit détecteur comprenantun premier capteur comprenant un iodure et un composé réactif choisi parmi l'amidon, l'amylose, l'amylopectine, le xyloglucane, le xylane, le chitosane, le glycogène, l'alcool polyvinylique ou un composé de l'alcool polyvinylique, la cellulose ou un composé de la cellulose, l'α-cyclodextrine, la théobromine et les polymères blocs d'oxydes de polypropylène et de polyéthylène, incorporés dans un bloc de matériau sol-gel absorbant dans l'UV mais pas dans le visible, et ses applications.
