Finally, this approach is versatile, and can be incorporated into a wide variety of reactors, for in situ characterization, and other instrumentation for hybrid measurements.

With minimal customization, compact submersible probes and a portable battery-operated DLS instrument were made as examples of potential implementation. In addition, use of fiber optic probes allows the beam path length to be as short as 1.6 mm while measuring at 90°, which reduces the likelihood of multiple scattering. Small volumes (<10 µL) can be measured, for example, by hanging a solution droplet from the fiber optic probe tips.

Also, complications associated with light refraction at the sample cell interface are avoided. It was observed that, even though an arbitrary scattering angle could be selected, aligning this instrument to obtain optimal detection efficiency can be completed in as little as a few minutes. This approach, while providing good sensitivity and high accuracy (e.g., measuring the size of latex standards to within 1% relative standard deviation), possesses several advantages not found, in their entirety, in existing DLS instrumentation. Details are provided that allow for academic researchers from diverse backgrounds to build this DLS instrument with minimal effort and at a low cost. We describe a method for constructing a fiber-optic-based dynamic light scattering (DLS) instrument from commonly available components, without a need for custom-made parts.
