A self-calibrating isotopic gas analyzer

摘要

A method of self-calibrating an isotopic gas analyzer, comprising the steps of: generating from a single gas sample having at least two isotopic components, at least two secondary samples having different concentrations of at least one of said isotopic components; measuring by means of said isotopic gas analyzer, isotopic ratios of said at least two isotopic components in said at least two secondary samples; and adjusting the calibration of said gas analyzer to correct significant differences found between said isotopic ratios. <IMAGE>
