Patent CA-2396015-A1 (CA)
Inventor: FERRANTE ANTHONY
IPC: G01N15/00
Filed: 2000-12-29
Abstract: A flow cytometer for the analysis of large particles or small multicellular organisms may experience unstable flow because of the large diameter of the flow chamber. The use of a sheath fluid or a sheath and sample with addition  of a viscosity-increasing agent to give a viscosity higher than that of wate r ensures that flow in the pre-analysis section will be fully developed lamina r flow, and that the flow in the analysis section will be laminar. This allows  accurate analysis and sorting of large particles or analysis and sorting of smaller particles at an increased rate of speed. Water-soluble polymers are preferred because they increase fluid velocity with negligible osmotic effects. A 0.9 weight % solution of polyvinyl pyrollidone with an average molecular weight of 1.3 million is particularly effective. Use of viscosity- increasing agents that cause minimal increases in surface tension of the flu id is also preferred.

Abstract: The present invention is a system (or apparatus) and method for processing fluids, especially waste streams from nuclear power plants, and other fluid media that may be carrying valuable or useful substances, in order to collect the substances carried by such media. The system uses sequential filtering and multiple passes to concentrate the substances, which allows the system to collect virtually all of the substances of interest to the user while reducing the volume of both the unwanted materials as well as the desired materials desired without affecting the purity of the fluid after processing. Additionally, the collected substances can be processed in-place, and without requiring any thermal processing prior to disposal of unwanted substances, or for the recovery and/or reuse of valuable substances. Furthermore, the system provides other desirable features including, but not limited to, a novel multi-purpose container, and an optional means to stabilize waste through in-place solidification.
