The NEW Cilas Nano DS combines dynamic light scattering and static light scattering measurement in a single optical system. This breakthrough technology makes nano particle characterization more accurate than ever. The Nano DS particle size analyzer provides you with the best accuracy, repeatability and resolution over the entire range of 0.3 nm to 10 microns.   
   
The Cilas Nano DS instrument combines static and dynamic light scattering for improving the reliability of results for bigger particles and polydisperse samples. The static light scattering is based on a spatial dependence of the scattered light. In DLS mode, the scattered light is time-dependent. These different approaches of the scattered light are based on two theoretical aspects which we develop in this document.
