NanoFab Tool: Wyatt Technologies Dawn Heleos II Dynamic Light Scattering and Field Flow Fractionation System
The Wyatt Technologies Dawn Heleos II dynamic light scattering and field flow fractionation system integrates several methods of field flow fractionation and light scattering to separate and measure nanoparticles in solution. The system can perform either hollow fiber flow field flow fractionation (HF5) or asymmetric flow field flow fractionation (AF4) to separate nanoparticle samples with highly polydisperse size distributions into sub-samples of nanoparticles of nearly uniform size. The system can measure the nanoparticle size distribution using simultaneous static and dynamic light scattering measurements on monodisperse sub-samples of nanoparticles. The system ensures repeatable results by allowing for automation and temperature control throughout the nanoparticle characterization process.
24 bit analog to digital signal processing converters for maximum noise rejection without signal distortion of light scattering and auxiliary signals.
