Abstract: A portable sampling unit capable of separating particulates, including biological organisms, from gaseous fluids such as air. A combined particle impact collector and fan is used to both move fluid through the sampling unit and to collect particulates. In one embodiment, the combined particle impact collector is a disposable unit that is removed and replaced with a fresh unit after each sampling period. The disposable unit is placed in a rinse station, where a liquid sample is extracted for later analysis. Alternatively, a disposable detection unit is incorporated in the sampling unit to provide real time detection of chemical toxins and/or biological pathogens. Preferably, the detector unit includes micro-fluidic channels so that a minimum amount of sample and test reagents are required. In another embodiment, the combined impact collector is integral to the sampling unit, rather than a separate disposable item.

Abstract: A method and apparatus for purifying air to deactivate toxic chemical and biological species such as Sarin, mustard gas, phosgene, cyanogen chloride, Anthrax spores, E. coli bacteria, Salmonella bacteria, Hepatitis virus, and Norwalk virus. The apparatus comprises a reaction chamber coupled to a counterflow heat exchanger. Incoming contaminated air is directed through a heating side of a counterflow heat exchanger to preheat it. The air is further heated to a temperature of at least 200° C., which is sufficient to deactivate common biological toxic species. Optionally, the reaction chamber may include a catalyst on a surface area over which the heated air is directed, which enables a thermocatalytic reaction that is particularly effective in deactivating biological and chemical warfare agents, such as anthrax and Sarin. Portable embodiments of the invention are useful in both military and civilian air purifying applications, while fixed installation of the apparatus are useful in deactivating toxic species from the air in areas where food is prepared or stored, or in purifying air in the environment of a living space.

Abstract: A handheld device for detecting the presence of biological and chemical airborne particles. The device collects a sample by drawing air in through a filter that allows air t pass through but collects particles in the air that are larger than the pore size of the filter, which may be selected to meet the user's needs. The filter is then subjected to an optical detection assembly that utilizes UV light directed on the filter and detects visible light emitted by any collected particles via a photomultiplier tube. Prior to collecting a sample, the filter is subjected to the optical detection assembly to generate a baseline reading, which is compared with the test results of the collected sample to determine the presence or absence of particles, such as mold.

Abstract: A method and apparatus for removing concentrated spots of collected particulates from an impact collection surface, and transferring those particulates into a container suitable for preparing a liquid sample. A jet of fluid can be utilized to remove and transfer the particulates. If a liquid jet is employed, care is taken to minimize the quantity of liquid to avoid unnecessarily diluting the sample. A mechanical scraper can alternatively be employed to remove and transfer the particulates into the container. The scraper can be rinsed with liquid or vibrated to remove the particulates. Alternatively, the portion of the surface containing a specific spot of particulates can be removed and placed into a container.
