Soluble xylo-oligosaccharide (XOS) concentrations vs total solids concentration of process samples. A Early and waste samples, B late stream samples. Solid black lines in each plot represent the line of equivalence, while the solid lines through data points represent the linear regression. The slopes of the linear regression fits are a measure of the average XOS purity in these samples (50.2% for early and waste stream sampling locations and 80.1% for the late stream sampling locations)
