Nature Protocols, Published online: 22 January 2026; doi:10.1038/s41596-025-01316-8This protocol isolates lignin from various types of biomass, screens for high-quality lignins, and uses them to directly prepare lignin adhesives without chemical modification, the performance of which is then assessed. It produces lignin adhesives with light colors and superior properties.

Lignosulfonates (LSs), a large-scale by-product of sulfite pulping, are currently the most widely produced and utilized lignin derivative. Like other lignins, LSs are characterized by an extremely complex irregular structure, and their distinctive feature is the presence of sulfo groups in the side chains of the phenylpropane structural units. The present study, for the first time, proposes a mass spectrometric (Orbitrap) methodology for characterizing the chemical composition of LSs based on the use of negative ion mode atmospheric pressure ionization techniques and chemometric approaches to the data treatment. The LS ionization efficiency increases in the series ESI
