This webinar will cover method development for samples dispersed in liquids. This will include a discussion of factors affecting the measurement, such as sampling and dispersion, and the relative importance of these factors in different particle size ranges. We will then suggest some routes that you can follow to develop robust methods for laser diffraction measurements in wet dispersion.
