SEC-dRI-MALLS

Size exclusion chromatography (SEC) fractionates macromolecules according to their sizes. Light scattering detector (MALLS) determines absolute molar mass and radius associated to analytes during the fractionation. SEC could be run with aqueuous carrier but also in organic mode and could be on-line coupled with the ICP-MS.
