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. The process includes periodically recording spectra arising from the near-infrared spectrometer, mathematically transforming the spectra, computing at least one quality criterion, intercomparing two sets of spectra after transformation, and tracking the evolution of this criterion over time. The process finds its application in the chemical, petroleum, pharmaceutical, cosmetological, and agro-food industries.
