Description: Chemical images help understanding of wood properties, durability, and cell wall deconstruction for conversion of lignocellulose to biofuels, nanocellulose and other value added chemicals in forest biorefineries. We describe here a new method for nondestructive chemical imaging of wood and wood-based materials at the micro-scale to complement macro-scale methods based on X-rays, acoustics, and georadar. Chemical detection, mapping and digital image construction were obtained with a high resolution Fourier transformed infrared microspectroscopy facility that obtains infrared light from a recently constructed beamline at the University of Wisconsin Synchrotron Radiation Center, Madison, Wisconsin USA. The pioneering Infrared Environmental Imaging (IRENI) facility is equipped with a unique design for illuminating and analyzing samples, enabling rapid FTIR data collection, high spatial resolution (pixel size of 0.54×0.54 µ2), and computer-generated images of lignin, hemicellulose and cellulose in wood cell wall layers of commercially important Pinus taeda L. and Populus deltoids Bartr.
Keywords: wood, poplar, pine, chemical imaging, FTIR, lignocellulose, IRENI, synchrotron
