Webb1 okt. 2024 · Even though NIR spectroscopy is based on the Beer–Lambert law, which clearly relates the concentration of the absorbing elements with the absorbance, the measured spectra are subject to spurious signals, such as additive and multiplicative effects. The use of NIR spectra, therefore, requires a preprocessing step. This article … Webb1 nov. 2024 · Several pre-processing techniques were applied to the spectra, such as the Savitzky-Golay second derivative (SGD2), Savitzky-Golay smoothing (SGS), area …
