The invention relates to a process and to an apparatus for providing a gaseous substance for the analysis of chemical elements or compounds. In one embodiment, a starting substance is continuously admixed with a reagent substance. This results in a gaseous reaction product which contains information about the elements of the starting substance, and a residual substance. The gaseous reaction product is separated from the residual substance and removed for analysis. One application is the isotopic analysis of oxygen or hydrogen from water. |
