Dynamic Light Scattering

Dynamic light scattering (DLS) measures the speed of small particles, polymers and macromolecules dispersed or dissolved in a liquid as they undergo Brownian motion. This motion causes laser light to be scattered at different intensities, and analysis of these intensity fluctuations yields the velocity of the Brownian motion, hence the particle size using the Stokes-Einstein relationship. Particle sizes of less than 1nm can be measured with established applications in biopharma, drug delivery, food research and environmental monitoring.

Our Delsamax series of dynamic light scattering particle analyzers can size particles of extremely small dimensions and low sample volumes. The Delsamax Core can size particles as low as 0.4 nanometers (nm), with sample volumes as low as 1 microliter (µl). The DelsaMax Pro meanwhile features 32 sensitive detectors to assess the distribution of particles in suspensions and emulsions in just a few seconds.
