Detection of incipient brown rot decay in wood by fourier transform infrared spectrometry
D D Nicholas, T Schultz
Fourier transform infrared spectrometry was evaluated as a possible method for detecting different levels of brown-rot decay in pine sapwood. By using first derivative spectra and regression analysis, an equation based on 4 absorption peaks, normalized with an internal standard peak, was developed. The correlation between weight loss and absorption was highly significant indicating that this is a valid method for detecting incipient brown-rot decay.
