Characterization of polymers by dynamic light scattering

The dynamic light scattering (DLS) method is introduced with an emphasis on visual cues in the raw data, followed by ways to extract quantitative information about size and size distributions from the data. The limitations of data analysis are discussed. The physical underpinnings of the method are presented without heavy reliance on equations. Although most users will purchase an instrument, design considerations are discussed so that buyers can appreciate how it works. Associated lab gear for preparing dust-free samples is discussed. The oft-ignored opportunities of depolarized DLS are considered. DLS is compared to other scattering methods and to alternative techniques. A small selection of applications concludes the chapter, in the hope that users might see their particular needs reflected in the activities of other researchers.
