Method and system for carbon isotopic ratio analysis in natural gas

Abstract

The present invention describes a system and method for analyzing carbon isotope ratio in natural gas. Said system comprises a sample injection vessel (1), a chromatograph (2) comprising a first chromatographic column (3) and a second chromatographic column (5), in which a combustion reactor (4) is presented between said first and second chromatographic columns, external to the chromatograph (2), and in which an isotope ratio mass spectrometer (6) is connected to the output of the second chromatographic column (5) and feeds the data system (7) with the results found for the sample in order to generate the chromatogram. In a second modality, the method of analyzing the carbon isotopic ratio in natural gas comprises the use of said system, which allows greater separation between the nitrous oxide and carbon dioxide components, eliminating the interferences found in the state of the art.
