Column screening for the separation of lignin-related phenolic compounds in lignosulfonate lignin using ultra-high-performance supercritical fluid chromatography
Introduction: This study attempts to optimize the choice of stationary phase for the separation of lignosulfonate lignin compounds using supercritical fluid chromatography coupled to mass spectrometry. Background: Lignin is a potential renewable source of phenolic compounds. Lignosulfonate lignins are produced during pulping processes producing very complex mixtures, which are challenging to anal
