LS Instruments

Dynamic Light Scattering (DLS, also known as Photon Correlation Spectroscopy or Quasi-Elastic Light Scattering) is one of the most popular light scattering techniques because it allows particle sizing down to 1 nm diameter. Typical applications include emulsions, micelles, polymers, proteins, nanoparticles or colloids. The principle is simple: The sample is illuminated by a laser beam and the fluctuations of the scattered light at a known scattering angle are detected by a detector. From a microscopic point of view, the particles scatter the light and thereby imprint information about their motion. Analysis of the variation of the scattered light provides information about the particles.

Founded by leading researchers in colloid physics, LS Instruments has built a reputation for instruments that can measure the most complex samples.

With modulated 3D DLS, LS Instruments has brought to market a unique technology that takes the strengths of classical DLS and adds more. Coupled with high-quality optics and high-power lasers, and a team of scientific experts, we offer solutions for the most advanced particle characterization challenges. This technological leadership makes our instruments indispensable in various sectors, including life sciences, personal care, chemistry, and advanced materials, as well as the food and beverage industry, meeting the needs of research and development.
