UCL/Anton Paar Particle Sizing Workshop: DLS DIA LD

This workshop is aimed at newcomers to particle characterization who are looking for a quick crash-course on dynamic light scattering, laser diffraction, and dynamic image analysis. We will introduce fundamental theory and concepts core to each methodology, the pros and cons of each and provide you ample time to get hands on with the equipment: the Litesizer DLS for Dynamic Light Scattering (DLS), Litesizer DIA for Dynamic Image Analysis (DIA), and the Particle Size Analyzer (PSA) for Laser Diffraction.

We will aim to cover the following topics:

► Dynamic Light Scattering (DLS) with the Litesizer DLS: Gain an understanding of the fundamental principles of DLS for particle size measurement. Explore the multifunctional capabilities of the Litesizer DLS, including its ability to measure zeta potential for surface charge analysis, molecular mass for sizing macromolecules, and the refractive index which is essential in optical property studies.

► Laser Diffraction with the Particle Size Analyzer (PSA): Learn the fundamentals of laser diffraction and how diffraction patterns are used to generate particle size distributions. This session will also cover how the properties of your materials can influence results and provide strategies to compensate for these variables. The PSA's capability to seamlessly measure both wet and dry dispersions makes it versatile for a variety of applications.

► Dynamic Image Analysis (DIA) with the Litesizer DIA: Understand how Dynamic Image Analysis provides a detailed assessment of particle shapes and sizes. This session will guide you through adjusting measurement settings to best represent your bulk material and how to interpret these results to analyse particle morphology, which is crucial for applications where particle shape influences performance.

In the practical sessions of our workshop, participants will gain hands-on experience with the instruments and software essential for particle characterization. We'll cover navigating the software interface, setting up and running measurements with actual samples, and interpreting the resulting data.
The workshop will be held at:
Room 421
Nunn Hall
20 Bedford Way
London
WC1H 0AL

Places will be limited to ensure a good ratio of delegates to tutors during the workshop.
