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