Polydispersity from a Gold Standard

How good can a gold standard be?   When performing dynamic light scattering (DLS) measurements, we sometimes encounter especially nice data. An interesting issue to consider is the level of data quality one can expect to achieve. What is the…READ MORE >

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

Is the distribution peak size or the overall mean size better? In dynamic light scattering (DLS) we measure the intensity autocorrelation function of the scattered light. We then fit this function to obtain a size. There are two main fitting…READ MORE >
