Abstract: A test for determining the presence of multi-valent metal contaminants, such as arsenic, mercury and chromium, when present in certain valence states and a system for removal of these contaminants from water. Multi-valent metal salts, for example, Cr+6, which are highly toxic, can be detected and potentially removed from water through a redox reaction by reaction with iron or cobalt salts to obtain a reductive elimination of the Cr+6 by conversion to Cr+3.

The system for the conversion of Cr+6 or other reducible metal salts to other lower valence states having less toxicity would rely upon introduction of a metal salt in the form of a reducing agent which would be introduced into the water allowing for a reduction/oxidation action to take place.

Abstract: A key problem associated with most types of separators based upon use of centrifugal forces is the difficulty such devices have with making absolute measurements of particle size and/or molar mass. By integrating means to produce and detect light scattered from samples undergoing centrifugal separation, particle sizes in the sub-micrometer range may be extracted from such measurements even in the presence of diffusion. The integration of light scattering detectors into an environment of high speed machinery is achieved by modifying the transparent surfaces of the sample holding region of the centrifuge. Such optical modifications allow the placement of stationary detector arrays able to collect light scattered by the samples during the brief collection times available. Three specific structures are addressed: A conventional disk centrifuge with a sample cavity integrated into the rotating structure; a disk centrifuge containing removable sample holding cuvettes, and an analytical ultracentrifuge.

The inlet and outlet pumps are operated by the controller, and the inlet pump may be operated to discharge separated components not collected by the blood separation system, whereby additional sample volume is added for ongoing operation.
