In "open ends" operation dispersion exists before and after the measuring point. This mode may be used with tracer studies when tracer is injected and sampled some distances from the ends of the vessel for the purpose of making accurate measurements of dispersion behavior. The boundary conditions are... 

Liquid-liquid mixing is widely used in liquid-liquid extraction operation, dispersion polymerization, emulsion polymerization, and so on. In general, in a mutually insoluble liquid-liquid system, one liquid is dispersed into another and the liquid with the smaller volume transforms into droplets however, when the volume of both liquids is almost identical, it is unclear which liquid becomes a droplet. 

In general, the technology used to disperse a powder before a characterization study should match the severity of dispersion forces that the powder will experience in use. Alternatively, if ultrasonics is used to generate a well dispersed powder, the analytical procedure protocol should be defined rigorously to avoid variations from operator to operator. Dispersing agents are frequently used, and great caution should be exercised because they can alter the structure of the system in a fundamental manner.f ... 

Using moderate agitation (800 rpm) provided by a Lightnin Mixer or similar variable speed unit and an impeller suitable for general mixing and blending operations, disperse or screen the Carbopol resin into the DI water. 

In industrial operations, dispersed sulfur, alkaline sulfide, or hypochlorite solutions are eflFective in trapping mercury. Sulfhydryl resins might be useful for removing alkylated forms of mercury (74), The mercury could be regenerated from these traps, or in the case of the dispersed mercury sulfide in sulfur, it might be disposed of in this very immobile form.
