Scattering Solutions is dedicated to the development of next-generation, low-cost analytical instrumentation based on light scattering optics. Scattering Solutions has developed an extensive portfolio of innovative technologies. These include new approaches to Dynamic Light Scattering (DLS) for colloid size and shape measurement; Surface Light Scattering Spectroscopy (SLSS) for determination of fluid surface tension, bulk and surface viscosities, and strain tensors; and new correlator designs for advanced signal processing.

In addition to developing products, we also offer consulting services and laboratory testing. Our expertise spans the fields of optical physics, engineering design, particle characterization, and surface chemistry.

Dynamic Light Scattering Instrumentation
Initial product development is focused on a low-cost Dynamic Light Scattering (DLS) instrument for size characterization of colloidal particles using innovative techniques that extend capabilities beyond those currently available in commercial instrumentation:

  • Very large dynamic range for analyzing a wide particle concentration range;
  • Small sample volumes (nano-liters and below);
  • Sample presentation in standard vials, optimized wedges, or as droplets;
  • Optical homodyne amplification to increase signal-to-noise ratio;
  • Fast FPGA correlation where the user chooses the number of channels;
  • Linear and fractal correlation with streaming data options;
  • Light-weight hand-held portable instruments for field use;
  • In-line instruments for process monitoring and control;
  • Depolarized DLS for nanoscale particle shape characterization.

The first image at the right shows a photo of the DLS prototype with a standard vial. The second image, visible by placing your pointer on the photo, is a graph of our product space, roughly charting particle size and fractional concentration for different applications. Also shown on the graph is the technology space, illustrating operation regions of our various technologies, most of which are incorporated in the prototype pictured.
