1. An isotopic gas analyzer for determining the ratio of at least a first and a second isotopic component of a gas, comprising:

  • at least one wavelength-stable source of radiation of wavelengths characteristic of at least one of said at least first and second isotopic components;

    at least a first sample chamber comprising a first sample of said gas to be analyzed;

    at least a first reference chamber containing a reference gas comprising said first and second isotopic components;

    at least a second sample chamber comprising a second sample of said gas to be analyzed;

    at least a second reference chamber containing a reference gas comprising said first and second isotopic components; and

    at least one detector detecting transmission through said at least first sample chamber and transmission through said at least first reference chamber, of radiation of wavelengths characteristic of said first isotopic component of said gas, and transmission through said at least second sample chamber and transmission through said at least second reference chamber, of radiation of wavelengths characteristic of said second isotopic component of said gas.
