International guidance documents relating to the use of laser diffraction, such as ISO133220:2009 and USP<429>, highlight the importance of using Certified Reference Materials to test the performance of laser diffraction systems during their lifetime. This is particularly important when laser diffraction is used as part of Quality Control operations or within audited laboratories, as testing using reference materials provides a baseline performance verification which provides assurance that any sample measurement variability relates to the product being tested rather than drift in the instrument performance.

The webinar will be presented by Dr Steve Ward-Smith, who is a member of the ISO TC24/SC4 Particle Characterisation committee where he advises on future guidance relating to the use and verification of laser diffraction systems.

Speakers

Steve Ward-Smith has worked for Malvern for 20 years and was the first full time technical specialist (Mastersizer with a little DLS) which he did for 12 years. For the last 8 years he's been working as a Key Account Manager and Key Account Technical Specialist looking after our key global customers on all technologies both from a commercial and technical perspective. As one of his other responsibilities he looks after the process applications personnel.

Steve has a PhD from the University of Nottingham in colloid science looking at protein –polyscaccharide complexes on oil droplets using laser diffraction, zeta potential, rheology and image analysis. He also has a Masters in Biomolecular Technology (essentially Physical Biochemistry) from Leicester University and a BSc in Chemistry from the University of Manchester.
