Dynamic light scattering is considered a low resolution technique, and typically a factor 3:1 can be resolved as separate peaks, see Nanoparticle Tips & Tricks. If you combine it with a separation such as size exclusion chromatography SEC or field flow fractionation FFF then the resolution is governed by that technique.
The latest Zetasizer series uses an approach called multi angle DLS which can improve the resolution to a factor 2:1
