METHOD FOR DETECTING THE TRANSITION OF PRODUCTS IN A CONDUIT

摘要

The invention relates to a method and a device for detecting the transition, in real time, between a first compound and a second compound, of a product that can contain such a first compound and/or such a second compound and circulates in a conduit for supplying said product. From the spectra taken for pure compounds, at least one spectral marker consisting of a function of a plurality of relevant absorbents of the spectra of such a pure compound is determined. Such a spectral marker enables the characterisation of the product to be characterised.
