Top tips to master optical filtering in dynamic light scattering

Dynamic light scattering (DLS) is an analytical technique for quickly and reliably determining the hydrodynamic diameter of particles in suspension. 

While this noninvasive technique is favored for its accuracy and ease of use, not all samples are straightforward. When measuring the size of more challenging particles, fluorescence and polarization filters can make all the difference. 

Join us to learn how they work and how to take advantage of them when running your DLS measurements. This capability is vital for anyone measuring quantum dots, fluorescing samples and other challenging samples. 

This session will cover:

• What is fluorescence and how it interferes with DLS measurements
• How to use optical filters for particle sizing measurements
• When and why to use vertical versus horizontal polarizers to improve results

Who should attend? 

• Scientists and engineers who use DLS on complex or fluorescent samples—including quantum dots, dyes/pigments, and particles that produce depolarized scattering
• Newcomers to DLS and existing users of Zetasizer Advance and Zetasizer Nano

What will you learn? 

• Understand what fluorescence is and how it interferes with DLS measurements
• Discover what optical filters do in DLS and the principles behind their use
• Learn how to use optical filters for particle sizing measurements
• Understand when and why to use vertical versus horizontal polarizers and learn how this improves results
