DWS is a versatile technique to characterize rheological quantities in a variety of colloidal systems. It can be performed without contact to the sample, and in sealed conditions, while accessing a large frequency range. Watch our latest webinar, in which Dr. Claude Oelschlager reviews the fundamentals of DWS microrheology, and presents applications related to biopolymers, protein solutions, worm-like micelles and clay suspensions.

In this live webinar, Dr. Mattia Usuelli (ETH Zürich) will introduce the concept of non-ergodicity in DLS, describe how to perform reliable measurements on gel-like samples, and discuss how to treat the resulting data. He will also present a direct application of this method in which non-ergodic DLS is used to extract the mesh size of amyloid fibril gels.

3D cross-correlation uses two simultaneous light scattering experiments on the same sample volume. This correlation scheme guarantees results in accuracy at any concentration and eliminates the traditional need for dilution. The Modulated 3D technology further improves the measurement rapidity and precision, by temporally separating the beams. This technology, introduced in 2010, is now the gold standard in light scattering.

Prof. Dr. Frank Scheffold is one of the inventors of the Modulated 3D light scattering technology. This webinar will explain the basics and illustrate its advantages by discussing several examples relevant to various industries.

Light scattering is a powerful, easy and in-situ way of characterize particle size and shape. A common approach is to conduct static light scattering measurements to obtain either the form factor, or the radius of gyration. In this webinar, Professor Matthias Karg from the Institute for Physical Chemistry reviews Particle Shape Characterization as done with Light Scattering.
