Dynamic light scattering (DLS), also known as photon correlation spectroscopy (PCS) and quasi-elastic light scattering (QELS), is a technique used to measure the Brownian motion (diffusion) and subsequent size distribution of an ensemble collection of particles in solution. It is used to monitor nanoparticles and zeta potential across a wide variety of products from pharmaceuticals to personal care products, general emulsions, surfactants and more.

In our earlier series of dynamic light scattering webinars, we introduced how the technology works, practical tips on sample analysis as well as data analysis. In this session, we will conduct a virtual demonstration of our Zetasizer Ultra, which is our latest model of our DLS range of instrumentation.

During this webinar, our specialists will run a variety of samples and demonstrate the new features of the Zetasizer Ultra as well as the data output in the software. We want to use this live virtual demo to showcase the speed, accuracy and repeatability of results as well as other value added features. For instance being able to conduct particle concentration measurements and measurement of complex materials in their undiluted states.

Learn about what's new:
1. Best possible resolution in DLS; possible with the Zetasizer Ultra's Multi-angle Dynamic LIght Scattering (MADLS) feature. See how MADLS incorporates back, side and forward detection angles resulting in the best possible 1:1 resolution, accurate and repeatable results.

2. Zetasizer Ultra's new and unique features - ‘adaptive correlation’ and Neural network based AI for guidance- not only enable significantly faster measurement time. The user also gains in terms of having a better understanding of the sample or sampling process.

3. Particle concentration measurement is also possible, as an extension of MADLS. This is calibration free.

4. Unique accessories such as the micro-capillary cell help measure ‘complex materials’ in their most desired ‘as it is ‘ or undiluted state.

We will run our samples live for you to experience how simple and easy the measurement process is.
