Biomass molecular weight distribution
The molar mass distribution of biomass samples soluble in pure water or organic solvents (DMF, DMSO, and THF) is measured with gel permeation chromatography with a refractive index detector (GPC-RID). The system is calibrated with polystyrene and dextran standards. A Pullulan standard is also available upon request.
In the case of lignin samples, molar mass distribution is analyzed using size exclusion chromatography (SEC) coupled with a UV detector at 256 nm wavelength. The lignin is dissolved in a suitable solvent before analysis. The SEC system is calibrated with a polystyrene sulfonate standard. A borate buffer is used to set the pH for the eluent.
