The DynaPro NanoStar can be operated using microcuvette-based format to analyze size distributions and particle concentrations of proteins, nanomedicines, viruses, vesicles, emulsions, micelles and metallic nanoparticles.
Traditional batch dynamic light scattering
The DynaPro NanoStar uniquely combines two optimized 90° detections channels: one for DLS and one for static light scattering for determining hydrodynamic Radius (Rh) and Molecular weight. The NanoStar performs robust, accurate measurements with as little as 2 µL of sample.
On-Line with SEC-MALS Dynamic Light Scattering
Using DLS on-line with SEC-MALS will provide hydrodynamic radii and, in combination with MALS, the shape factor Rg:Rh of macromolecules > 10nm.
