ABSTRACT:
The invention relates to a process and to an apparatus for providing gas for isotopic ratio analysis. According to the invention, a gas is generated from an eluate of a liquid chromatograph (LC). Subsequently, the gas is separated from the eluate. Finally, the gas is fed to an instrument (IRMS) for isotopic ratio analysis.
