Liquid Optical Particle Counters: Digital Age

Abstract

There are many industries that use Optical Particle Counters (OPC) to monitor particle contamination in liquids. While liquid OPCs have evolved with time they have employed the same general light-scattering design principles. Now, NanoVision Technology brings particle counters to the digital age, utilizing a high density two dimensional array of high-efficiency detector elements. This technology allows any background light scattering by the chemical molecules to be differentiated from light scattered by particles within the fluid. The result is a significant reduction in false-positive counts within fluids with high levels of molecular scattering. The results of using this technology are discussed.
