A Comparison of Methods for Determining Macromolecular Polydispersity from Dynamic Laser Light Scattering Data
Polymers and High Performance Materials
Several different methods for extracting macromolecular polydispersity information from normalized intensity correlation functions obtained from dynamic light scattering have been proposed. However, detailed comparisons of these methods are lacking. We have proposed a new analysis method involving the GEX function in conjunction with function fitting. Computer simulated data, convoluted with noise, was used to compare our method with Constrained Regularization and the Subdistribution technique. In general our method yielded results at least as good as those from constrained regularization and is more operator independent. The subdistribution method yielded the poorest results.
