Abstract EN
This research addressed a rapid method to monitor hardwood chemical composition by applying Fourier transform infrared (FT-IR) spectroscopy, with particular interest in model performance for interpretation and prediction.
Partial least squares (PLS) and principal components regression (PCR) were chosen as the primary models for comparison.
Standard laboratory chemistry methods were employed on a mixed genus/species hardwood sample set to collect the original data.
PLS was found to provide better predictive capability while PCR exhibited a more precise estimate of loading peaks and suggests that PCR is better for model interpretation of key underlying functional groups.
Specifically, when PCR was utilized, an error in peak loading of ±15 cm−1 from the true mean was quantified.
Application of the first derivative appeared to assist in improving both PCR and PLS loading precision.
Research results identified the wavenumbers important in the prediction of extractives, lignin, cellulose, and hemicellulose and further demonstrated the utility in FT-IR for rapid monitoring of wood chemistry.
