Dynamic Light Scattering (DLS)

More details about this Instrument

The DynaPro NanoStar™ from Wyatt Technology is Dynamic Light Scattering (DLS) instrument that is used for the analysis of protein solutions, aggregates, buffers, nanoparticles, polymers, or other products in solution. In a DLS measurement, the time-dependent fluctuations in the scattered light are measured by a fast photon counter. The fluctuations are directly related to the rate of diffusion of the molecule through the solvent. Therefore, the fluctuations can be analyzed to determine a hydrodynamic radius for the sample (0,5 nm to 1000 nm). Molar mass range: 300 Da to 106 Da. Minimum concentration = 0,1 mg/ml.

Access Procedure: 
Users of the MRL Synthesis and Characterization Laboratory are required to go through two levels of training before they are authorized to perform data collection independently. The training consists of
  • General lab safety training, provided by the UCSB Environmental Health & Safety Department (EH&S).
  • Instrument training, conducted by development engineer or an authorized user delegated by the development engineer.
