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 all that’s…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, is it possible to recalculate…READ MORE >

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 >
