(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.
