There are two major commercial types of light-scattering particle size analyzers: Static Light Scattering and Dynamic Light Scattering. They are expensive, delicate, bulky, and must operate at extremely low particle concentrations. A fundamental mathematical model for high concentrations has been in need for decades and finally developed by the author after 25 years of research and development (METAMODELTM). UV-NIR spectroscopy has a long successful history for molecular characterization of gases, liquids, or solids but commercial particle size analyzers based on this powerful principle do not exit. Seven impediments for its presence in the market are identified and their resolution either described as already accomplished by the author or achievable with a high probability of success during Phase I. It is our long-term goal to develop a commercial UV-NIR high dynamic-range, miniaturized, robust spectrometer for particle size analysis in the range 1 nm to 10 um (METASIZERTM). During Phase I, a breadboard prototype to demonstrate feasibility will be developed. We firmly believe that, due to its expected superior performance and lower cost, our innovation and its derivatives could revolutionize the field of particle sizing in both diluted and concentrated particulates. Applications are innumerable ranging from materials science through pharmaceuticals to environmental.
