"Like other techniques, NIR spectroscopy has also some drawbacks. The low sensitivity of this technique restricts the determination of the active principles with less than 0.01% (w/w). NIR spectroscopy is an indirect method which requires a reference method, Chemometric techniques - statistical and mathematical procedures - to extract, and interpret spectral information acquired from the sample NIR spectra"
