Method of preparing h2s for isotopic analysis.

摘要

Invention Patent: B "METHOD OF PREPARING H ~ 2 ~ S FOR AN ISOTOPIC ANALYSIS" D. Method to prepare the sulfur and / or hydrogen contained in a small amount in the sulfurized hydrophene: 1) the oxidation of H ~ 2 ~ S is carried out at a temperature and duration chosen in order to achieve the total oxidation of H ~ 2 ~ S in SO ~ 2 ~, and at the end of this stage, at least two products are obtained: SO ~ 2 ~ and H ~ 2 ~ O; 2) the two SO ~ 2 ~ and H ~ 2 ~ O products obtained at the end of step 1) are separated; 3) the isotopic measurement of the sulfur contained in the sulfur dioxide obtained in step 2), and / or 4) the H ~ 2 ~ O obtained in step 2) is contacted with an agent capable of reducing water in the form of hydrogen; and 5) the isotopic measurement of hydrogen is performed.
