The WyattQELS™ dynamic light scattering (DLS) module is designed to be integrated into Wyatt DAWN® or miniDAWN™ multi-angle light scattering (MALS) detectors so as to establish particle sizes on-line together with the Eclipse™ asymmetric flow field-flow fractionation unit or basic size exclusion chromatography.
When coupled with the ASTRA® light scattering chromatography software, precise nanoparticle and macromolecular size distributions in a solution can be procured.
The main features of the WyattQELS™ dynamic light scattering (DLS) are:
- Range of hydrodynamic radius Rh with the flow: 1-300nm with DAWN HELEOS
- Range of hydrodynamic radius Rh without flow: 0.5-1µm
- Range of hydrodynamic radius Rh with the flow: 1-40nm with miniDAWN TREOS
