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 >

Can one calculate a PDI value excluding a small aggregation peak? For example if the main particle species is ~100nm and there is a small contribution (2% by intensity) from a peak at 5 microns. In that case, is it…READ MORE >

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 >
