Light scattering with the Zetasizer owes part of its success to the ease of use integral in its default DTS software. The intuitive windows environment lets you setup a measurement (either in “manual” or in “standard operating procedure” mode) and…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 >
