Fractionation of an Oxidative Lignin Depolymerization Mixture Using CPC

Lignin is an abundant phenylpropanoid polymer found in all plant matter. It has historically been treated as an impurity in the paper pulping and ethanol biorefinery industries where it is burned as a low-value fuel or sold at low prices. However, developing higher-value applications of lignin would help biorefineries operate at higher efficiencies. In this app note, a two-dimensional separation is conducted using centrifugal partition chromatography (CPC), which helps demonstrate the value of CPC as a tool for gaining deeper insights into depolymerization mixtures for biomass facilities.
