Web9 dec. 2024 · Multiplicative scatter correction (or multiplicative signal correction, MSC) and standard normal variate (SNV) scatter correction are the preprocessing techniques most widely used to remove the scattering effects caused by variations in the physical properties of samples [5,7]. The MSC method needs to estimate the intercept and slope … WebMultiplicative scattering correction (MSC) or derivation can eliminate these variations [117, 118]. [Pg.219] Compared to spectra obtained in the mid- infrared region, NIR spectra contain fewer, less resolved, peaks. Due to scattering and other effects, a set of NIR spectra on similar samples often exhibits constant baseline offsets from one to ...
