In this third webinar in the particle sizing masterclass we look at method development and we concentrate on the techniques of laser diffraction and automated image analysis. The most important thing in method development is always to make sure that the results enable you to follow your production process or understand your product’s performance. With that in mind we look at how to work out how much sample you need to measure, the different options available for dispersing the sample (and how you might choose the best one for your sample) as well as how to set the appropriate measurement conditions. We use a couple of case studies to illustrate these three main factors, and after that you should have a good idea of how to start developing methods for your materials.
