ABSTRACT:
A process is provided for the detection and qualitative and quantitive differentiation of naturally deuterated molecules.
This process consists in (a) preparing a standard by mixing a commercially available hydrocarbonic product with its artifically deuterated analogue, (b) introducing this standard into the measuring cell of the RMN analysis apparatus; (c) adding the product to be analyzed to the cell and (d) introducing the cell into the RMN (D) apparatus and recording the spectrum of the deuterium which is compared with the RMN (D) spectra of products of known geographical origin and from known chemical and/or biochemical sources, made beforehand with the same standard.
