Dyanamic Light Scattering - Common Terms DefinedMalvern Instruments
There are a number of sources of information that give a mathematical description of the terms used in light scattering. However, these will not usually give assistance in understanding their practical application.
The following list gives a definition, with notes on their specific use in the context of dynamic light scattering.
The Z-average size (or Z-average mean) is used in dynamic light scattering as a parameter also known as the cumulants mean. It is a primary and most stable parameter produced by the tecnique.
