Latest Patents

Isaac B Roll's latest patents include devices and methods for the determination of bioavailability of pollutants. One of his inventions is a method and system that enables the determination of kinetic rates of reaction within a fluid of interest. This system includes directing fluid flow exiting a test bed to a multi-port switching valve. The multi-port switching valve switches the fluid to various channels connected to interchangeable in-flow extraction cartridges. Analytes of interest from the fluid flow are captured on an extraction medium to accumulate over time. Rates are determined by sequentially channeling the fluid through each of the plurality of flow paths for a preselected time duration, analyzing the extraction cartridges, and computing the kinetic rate of reaction.

Another patent focuses on contaminant mass collection in saturated sedimentary environments for bioavailability determination. This invention features a casing that includes a screen between the environment subject to sampling, such as saturated sediment, and the device itself. The casing comprises a water intake zone, a pump, and sorptive media. The screened casing is secured to form an in situ device, which is deployed in the saturated sedimentary environment. The pump operates to concentrate analytes from the selected environment in the sorptive media, where the concentrated analytes include the analyte mass of time-weighted fluid samples.
