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.
Dr Mike Kaszuba: Michael Kaszuba is Technical Support Manager at Malvern Instruments Ltd. He has a PhD from the Polytechnic of Wales, where he studied the physical biochemistry of liposomes using nuclear magnetic resonance techniques. He followed this with postdoctoral research into liposomal drug delivery at the University of Manchester. Michael joined Malvern in 1996 as a Product Technical Specialist and two years later was appointed in his current role, responsible for the Product Technical Specialist and Application groups based in the UK.
