Course Description
A -day course that will bring personnel in the particle sizing field up to speed on the basics and importance of sampling for particle size analysis. The course will deal with 2 main objectives – determination of the minimum mass required for any required precision and the calculation of the best fundamental sampling error (FSE) based on the mass used in any particle size determination. We will point out the major issues with sampling including delimitation errors and provide limited advice as to the recommended routes to take a reasonable sample and the dangers of taking limited or unrepresentative samples. The course is suited to users of all particle size analysis techniques from sieves to light scattering and there will be a practical exercise for attendees.

Target Audience
Those with some practical experience of particle sizing techniques who want to isolate the issues associated with representative and non-representative sampling.
