Knowing the chemical composition of a substance provides valuable information about it. That is why numerous techniques have been developed to try obtain One them Near Infrared Spectrometry technique, non-destructive technique that analyzes electromagnetic spectrum in search waves certain length. The aim this project combine technology with machine learning detect presence milk, as well level c...

Fecal lipid content is usually determined by titrimetric or gravimetric methods, but these methods are time consuming and involve dangerous solvents. We have developed a new method of measuring fecal lipids by Fourier transform infrared spectrometry (FTIR) with an attenuated total reflectance accessory that is fast and requires no solvents. The spectra of stools from 4000 to 750 cm-1 were analy...
