Webinar: ‘Higher Resolution Particle Sizing with MADLS’

In traditional dynamic light scattering (DLS) experiments, the scattered light is detected at a single angle and then auto-correlated to determine the diffusion rate of the particles, and ultimately the particle size distribution.

Since the direction and the number of photons scattered depends on the size of the particles, for mixed particle sizes a single angle result may misrepresent the true particle size population.

Multi-angle dynamic light scattering (MADLS) overcomes many of these drawbacks by automatically combining correlograms from multiple measurement angles to give a robust, angular independent result, with improved resolution, which is suitable for comparison with data from orthogonal techniques.

In this webinar, Malvern Panalytical explains the basic principles behind the MADLS measurement on the Zetasizer Ultra and provides measurement examples.

The webinar will take place on 4 October from 10:30 (GMT-5:00) to 11:30.

Speaker Doug Hamilton received his PhD in Chemical Physics in 2012 from the University of Bristol. He joined Malvern Panalytical as a systems engineer and has worked primarily on the Zetasizer product range. Now a senior systems engineer, he contributed to the development of many new features in the Zetasizer Ultra and Zetasizer Pro. Doug is a keen rock climber and enjoys spending time out of the office on climbing trips.

Who should attend?

Anyone who is a user of DLS, is interested in DLS, or who faces challenges in particle size characterisation across technologies should attend the webinar. Attendees will learn that MADLS is a new capability that delivers robust, angular-independent, size determination of samples with the ability to discover previously hidden size populations.
