Abstract
A process for tracking and monitoring the operation of a unit for manufacturing a product and/or a near-infrared spectrometer fed with the product. This process includes computing at least one indicator of proper operation of the manufacturing unit and/or of the near-infrared spectrometer. A mathematical expression combines the values of work spectra and those of corresponding recomposed spectra. The evolution of these indicators is then tracked. The spectra are obtained by transformations of spectra emanating from the spectrometer and are recorded periodically. Application of this process is in the chemical, petroleum, pharmaceutical, cosmetological and agro-food industries.
