New method of detection and differenciation qualitative and quantitative composition of the molecules naturally deuterated, a device for implementing this process and application, in particular, the detection of the wines chaptalisation

摘要

The present invention relates to a method of detection and differenciation qualitative and quantitative composition of the molecules naturally deuterated. / p & & p & this process is characterizes in that: a) is to prepare a standard commercial hydrocarbon mixing a product with its deuterated artificially; b) is introduced the etalon in a measurement cell of the analysis apparatus by nmr; c) is added in the cell, the product to be analyzed, and d) is introduced the cell in the nmr apparatus d, and it records the spectrum of the deuterium and is compared to the nmr spectrum of the products from geographical chemical and biochemical and or sources known, carried out beforehand with the same standard. / p & & p & application, in particular, the detection of the chaptalisation of the wines.
