Patent ID: 8796035

Claim:
A method for sulfur characterization and quantification in a sample of sedimentary rocks or of petroleum products, wherein the following stages are carried out: heating said sample in a pyrolysis oven in a non-oxidizing atmosphere to a temperature resulting in release of pyrolysis effluents and production of pyrolysis residues, transferring the pyrolysis residues produced from said sample into an oxidation oven, heating the pyrolysis residues in said oxidation oven according to a temperature resulting in release of effluents from said pyrolysis residues, and continuously measuring the amount of SO 2 contained in the effluents released from said heating in the oxidation oven, oxidizing part of the pyrolysis effluents released from heating said sample in the pyrolysis oven and continuously measuring the amount of SO 2 contained in said part after oxidation.
