FAQ: Peak size or z-average size – which one to pick in DLS?

In dynamic light scattering (DLS) the intensity autocorrelation function of the scattered light is measured. This function is then fit to obtain a size. There are two main fitting algorithms which may confuse users: Cumulant (or z-average) size and polydispersity…READ MORE >
