Spectroscopic measurement method

A spectrometric measurement method of determining concentrations of components included in a medium of a given type exhibiting different compositions in different applications, the method comprising:

• for at least two different reference applications, wherein concentrations of different sets of at least one reference component included in the medium of the given type at the respective reference application are of interest:
• using a spectrometer, determining reference spectra of a plurality of reference samples of the medium present in the respective reference application and determining reference concentrations of the concentration of each reference component included in the reference samples;
• based on the reference spectra and the corresponding reference concentrations for each reference component, determining an asset for determining concentrations of the respective reference component based on measured spectra of the medium present in the respective reference application;
• and
• storing reference application data in a database, including the asset determined for each reference component and the respective reference component for which the asset was determined;
• and
• for at least one new application, wherein a medium of the given type includes a set of target components given by a combination of reference components, each of interest in at least one of the reference applications:
• for each target component, determining a target asset for determining the concentration of the respective target component in the at least one new application to be given by one of the assets stored in the database, which asset was determined for one of the reference components corresponding to the respective target component;
• based on the target assets, determining a new model for determining concentrations of the target components based on measured spectra of the medium present in the new application;
• using a spectrometer, determining measured spectra of the medium present in the new application;
• and
• based on the measured spectra and the new model, determining measurement results of the concentrations of the target components and providing the thus determined measurement results.
