Study of the scattering effects on NIR data for the prediction of ash content using EMSC correction factors

Abstract: Scattering effect is a really common physical phenomenon during near‐infrared analysis. It is an undesired variation in the spectral data due to a deviation of light from a straight trajectory into different paths. The nonlinearities introduced can be handled by using spectral preprocessing techniques. The situation is completely different when the parameter of interest is physical by nature, such as ash content, in this case removing the physical artifacts of scattering would be negative for the final model. … Show more

“…As reported by [15], moisture prediction could be influenced also by the presence of cellulose. The peak at 1404 (2 gr ) nm was assigned to water presence and corresponded to the 1st overtone of O-H stretching vibration [9]. Even the peak at 1435 (3 gr ) nm was related to water, corresponding to the 1st overtone of O-H stretching vibrations, while the peak at 1577 (4 gr ) nm was related to interchain O-H bonds of cellulose.…”

“…Instead, the band at 1497 (5 gr ) nm was related to the 1st overtone of O-H stretching vibrations of hemicellulose [39]. The peak at 1342 (3 gr ) nm corresponds to C-H combination bands [9] and the peak at 1379 (4 gr ) nm to C-H bending vibrations [27]. Lastly, the peak at 1546 (6 gr ) nm was related to C-H stretching vibrations of cellulose [42].…”
