Dynamic Light Scattering  (DLS).  Light scattering can be used to get information on particle size, shape and heterogeneity.  The DynaPro NanoStar is available for Dynamic Light Scattering (DLS) measurements.  It is capable of measuring samples ranging in size from 0.5 nm to 1000 nm at concentrations as low as 0.1 mg/ml. The NanoStar also has a dedicated Static Light Scattering (SLS) detector so not only can it measure hydrodynamic radii, but absolute molecular weights as well.
