In this short webinar we will be looking more closely at why %CV of particle concentration measurements vary more when there are aggregates present in the sample.

We will look at how the calculation of concentration from a multi-angle dynamic light scattering (MADLS) measurement in a Zetasizer Ultra is performed and identify the factors that may affect the repeatability and accuracy of these measurements. We will also outline some general guidelines for best practice for these types of measurements.
