  • Patent number: 7284448
    Abstract: An improved method and apparatus for simultaneously monitoring the fluid flux and the target chemical mass fluxes in fluid flow systems is provided comprising the use of a body or shell that is inserted into the flow field. Inside or outside this body is a bundle of one or more permeable sorptive columns. The extremes of each column are hydraulically connected to the outside flow field around the body of the device through a pair of small openings in the body. The known non-uniform flow velocity distribution around the body of the invention causes a pressure difference between pairs of openings used to connect internal or external column units. A preferred shape of the body is a hydrofoil. Alternatively, instantaneous measurement of the fluid flux and contaminant composition is possible using pressure transducers and a chemical sensor.

  • Patent number: 6401547
    Abstract: An improved method and apparatus for simultaneously monitoring the fluid flux, and the dissolved contaminants fluxes, in a flow field is provided comprising the use of a permeable unit containing an insoluble sorbent matrix that retains dissolved contaminants. The matrix may also contain tracers that can be displaced by the fluid flow. The method of monitoring comprises placing permeable units in contact with the contaminated flow field, thereby allowing contaminants to flow through the permeable unit and be sorbed on the insoluble sorbent matrix. Sufficient time is allowed for the contaminant concentrations in the flow field to reach equilibrium. The permeable unit is then removed from contact with the flow field and analyzed to determine cumulative contaminant fluxes and cumulative fluid fluxes.
