Publication number: 20230349871Abstract: An analytical method makes use of an oxygen-containing source having a predetermined content of an isotope of oxygen zO, which is not the same as natural composition and distribution of oxygen isotopes, to detect and/or quantify oxygen in oxidizable compound(s). The analytical method allows detecting and/or quantification with relatively high precision and accuracy oxygen in oxidizable compound(s), even at low content. The method is easy to implement and can be used for in-line analysis.Type: ApplicationFiled: June 30, 2023Publication date: November 2, 2023Applicants: TotalEnergies OneTech, UNIVERSIDAD DE OVIEDO, UNIVERSITE DE PAU ET DES PAYS DE L'ADOUR, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE (CNRS)Inventors: Pierre GIUSTI, Jorge RUIZ ENCINAR, Mariella MOLDOVAN, Brice BOUSSIERE
