Diffuse reflectance mid-infrared Fourier transform spectroscopy of cellulose-based materials
Diffuse Reflectance mid-Infrared Fourier Transform (DRIFT) spectroscopy has been applied to the analysis of cellulose-based materials including wood, paper, and paper products. High-quality DRIFT spectra representing 1 mm spatial resolution on the substrate were obtained from different locations on the sample using a mechanical positioning technique. The analysis of the spectra results in spectral images showing the spatial variation in the chemistry of the sample. Chemical variations in cellulose-based samples have been observed due to variations in ink content, coating thickness, and concentration of phenyl and carbonyl groups associated with lignin. {copyright} {ital 1998 American Institute of Physics.}
