Various Reference Samples of lignin are available to ILI members as references for analytical testing or for research purposes. The EUROLIGNIN Round Robin Samples include a Soda lignin, a Kraft lignin, a Lignosulfonate and a Steam explosion lignin. These samples have been widely tested and documented. The Molar Mass Standard Samples are from a Soda lignin fractionated in four parts by ultrafiltration and are available for referencing and calibration of GPC systems. They have also been extensively analysed in the LignoAnalyse project.
For Research Samples, ILI has contacts with virtually all lignin producers in industry and research (all public biorefinery research project involving lignin are member of our umbrella programme. On request, Access to Commercial and Experimental Lignins is given to members, through personalised contact details and support for obtaining the samples.
