Application Note: AF4-MALS as a promising tool for industrial lignosulfonate analysis
31 March 2020

In this application note, Wyatt Technology presents a novel approach to the analysis of the molar mass of water-soluble lignosulfonates (LS) by means of AF4-MALS. The method allows for the direct injection of non-purified industrial samples and aims to provide accurate and precise data about LS molar mass distribution, promising a simple, fast and less labor-intensive alternative to standard GPC analysis.
