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.

More information
Who should attend?
All users of Mastersizer systems.
Anyone engaged in performance verification of Mastersizer systems.

Why attend?
In this webinar, we will introduce an important update to the way Malvern Panalytical support our customers in ensuring their laser diffraction systems are working as designed. Performance testing of Mastersizer systems is based around the use of Malvern’s single-shot glass bead Quality Audit Standard (QAS). We will soon release a new batch of this material (Batch 3), which may lead to a requirement for our customers to update their own system test procedures. We will describe the properties of this new QAS batch, and will reviewing how it’s use plays an important part in system testing in line with industry standards.

What will you learn?
The process by which Mastersizer laser diffraction systems are verified, and how the introduction of Malvern Panalytical’s new Quality Audit Standard (Batch 3) will support system testing.

Rheology is defined as the science of deformation and flow and in particular refers to materials that show viscoelastic or non-Newtonian behaviour when stressed. Such materials include suspensions, emulsions, polymer solutions and foams to name but a few.

Part 2 of this two part webinar series will focus on viscoelasticity, introducing the basic concepts and tests that can performed on a rotational rheometer to measure viscoelastic properties.

More information
Why attend?
Rheology is important across a wide range of applications and industries and a basic understating of the subject can help to better understand your processes and applications.

Who should attend?
Anyone who is interested in viscoelasticity who would benefit from a basic introduction to the concepts and measurement protocols.

What will they learn?
How to measure and describe the viscoelastic properties of your materials under process and application relevant conditions.
