The WyattQELS™ Dynamic Light Scattering (DLS) Module

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 solution can be procured.

Key Features

The main features of the WyattQELS dynamic light scattering (DLS) are:

  • Range of hydrodynamic radius Rh with flow: 1-300nm with DAWN HELEOS
  • Range of hydrodynamic radius Rh without flow: 0.5-1µm
  • Range of hydrodynamic radius Rh with flow: 1-40nm with miniDAWN TREOS
