Figure 2From: Rapid analysis of composition and reactivity in cellulosic biomass feedstocks with near-infrared spectroscopy Predicted versus measured values of glucan, xylan, and lignin for the 232 calibration samples. The x-axis represents constituent values obtained from primary methods measured on a percent dry weight basis (wt%). The y-axis represents values for composition obtained by prediction from the PLS-2 calibration equation. Ash is not pictured here for ease of visibility.Back to article page
