Recent Developments in Deep Eutectic Solvents Applications in Liquid Chromatography: 2019–2025

Journal of Separation Science, Volume 48, Issue 5, May 2025.
ABSTRACT Deep eutectic solvents (DES) are used as mobile phase and stationary phase modifiers, or as for the stationary phase itself for thin layer/liquid/supercritical chromatography. Their specific properties can improve the separation selectivity, reduce peak tailing, and shorten the separation time.
