Figure 3From: A holistic high-throughput screening framework for biofuel feedstock assessment that characterises variations in soluble sugars and cell wall composition in Sorghum bicolorFTIR spectra of pure sugars, S. bicolor juice, and the PLS model calibration set. FTIR spectral fingerprint region collected from: (A) pure sucrose, glucose, fructose, and H2O; and (B) S. bicolor juice containing low, medium, and high concentrations of sugars and a low and high mixture of pure sucrose, glucose, and fructose against a H2O background. (C) Set of 216 samples consisting of varying mixtures of sucrose, glucose, and fructose making up the calibration set. Wavenumbers between 1,190 to 850Â cm-1 were plotted. X-axis represents spectral wavenumber (cm-1) and y-axis units are arbitrary. FTIR, Fourier transform infrared; PLS, partial least squares.Back to article page
