Abstract
A submersible light scattering probe for the absolute characterization of polymer and colloid solutions includes a ring member made of a preferably dark, opaque material, having embedded therein a plurality of optical fibers which can be connected to optical detectors remote from the probe. The ends of the optical fibers are preferably in direct contact with the fluid being tested. Instead of submersing the probe in a fluid, fluid can be caused to flow through the probe, placed in the probe, or placed in a transparent vessel placed in the probe. Individual large scattering particles can also be detected, counted, and characterized at the same time absolutes characterization of the polymer or colloid solution is performed.
