This webinar will provide a general introduction to measuring particle size using laser diffraction. We will introduce the technique of laser diffraction as well as some basic principles of particle sizing. This will include an overview of the process of making a laser diffraction measurement, what data is recorded and how a particle size distribution is calculated. How these results compare to particle size results from other techniques will also be discussed, as well as a range of applications of laser diffraction particle sizing.
