It covers a broad size range from the lower nanometer range up to several micrometers. DLS provides information on the mean particle size as well as on particle size distribution. DLS doesnt measure the size of the particles directly, it measures the Brownian. Dynamic light scattering is a well-established, standardized technique for particle size analysis in the nanometer range and has been used for about 40 years.

Walker, Fundamentals of Physics (Wiley, New York, 1997), 5th ed., Chap. DLS is used to size particles from below 5 nm to several microns. A good source of such particles is PolyScience, 6600 W. Dynamic Light Scattering (DLS) is also known as Photon Correlation Spectroscopy (PCS). For example, older models of Malvern, Langley Ford, and Brookhaven correlators should work fine.
