The WyattQELS™ dynamic light scattering (DLS) module integrates into Wyatt DAWN® or miniDAWN™ multi-angle light scattering (MALS) detectors for determining particle sizes on-line along with the Eclipse™ asymmetric flow field-flow fractionation system or standard size exclusion chromatography.
This feature is used in the ASTRA® light scattering chromatography software for providing precise nanoparticle and macromolecular size distributions, in solution.
- Range of hydrodynamic radius Rh with flow: 1 to 300 nm with DAWN HELEOS
- Range of hydrodynamic radius Rh with flow: 1 to 40 nm with miniDAWN TREOS
- Range of hydrodynamic radius Rh without flow: 0.5 to 1 µm
