Dynamic Light Scattering (DLS), sometimes referred to as Photon Correlation Spectroscopy or Quasi-Elastic Light Scattering, is a technique classically used for measuring the size of particles typically in the sub-micron region, dispersed in a liquid. The sensitivity of some modern systems is such that it can also now be used to measure the size of macromolecules in solution.
In this presentation Dr Mike Kaszuba will summarize how the technique works, what its size and concentration limits are, and discuss its advantages and disadvantages.
