摘要:
A method and apparatus for neutralizing biological and/or chemical warfare agents using an ozone-containing solution. The ozone-containing solution is produced by combining ozone-containing gas with an ozone vehicle, such as an organic solution. The ozone-vehicle prolongs the shelf life of the ozone to allow for extended periods of storage. A storage container is used to store the ozone-containing solution and facilitate its transportation to an environment contaminated by the biological and/or chemical warfare agents, or near a potential site for biological or chemical attack. The ozone-containing solution is drawn out of the storage container to apply it to a contaminated environment.
摘要:
A method and apparatus for monitoring the concentration of a detergent in a detergent solution. A capacitive sensor is exposed to the detergent solution, and electrical properties of the capacitive sensor are responsive to changes in the concentration of detergent in the detergent solution.
摘要:
A method and apparatus for formulating and controlling concentrations of deactivating chemicals in a gas mixture inside a chamber. The gas mixture may include chemical components that are deactivating chemicals, as well as chemical components that are base chemicals, acting as a dilutant for the deactivating chemical, or as a vehicle or carrier for the deactivating chemical. A capacitor is exposed to the gas mixture, wherein the gas mixture comprises a dielectric material between the plates of the capacitor. Permittivity of the dielectric is affected by the relative concentrations of the chemical components, and thus a measurement of the capacitance is used to determine the concentration levels of multiple chemical components in the gas mixture.
摘要:
A contaminant detecting system for determining the presence of a miscible or immiscible contaminant in a fluid. The fluid acts as a dielectric between the plates of a capacitive sensing element. The measured capacitance value varies in accordance with the composition of the fluid, to indicate the presence or absence of the contaminant in the fluid.
摘要:
A mobile deactivation apparatus for deactivating contaminants within a defined region that includes a source of a vaporous deactivating agent, a gas handling system, a support member, a drive means, a control system, and a power system is disclosed. The gas handling system dispenses the vaporous deactivating agent to the defined region. The support member is movable in the defined region and supports the source of the vaporous deactivating agent and the gas handling system. The support member can be propelled by the drive means. The control system is programmed to control the operation of the gas handling system and the drive means. A power system is provided to supply power to the mobile deactivation apparatus.

摘要:
The present invention provides a method and apparatus for removing chemical sterilant molecules from a medium, such as a carrier gas. In one embodiment, the apparatus includes a housing that defines an internal cavity. The housing has an inlet and an outlet fluidly communicating with the internal cavity. An electrode is dimensioned to be received in the internal cavity of the housing. The electrode is made of a material that is chemically active with respect to molecules of a chemical sterilant and conductive to electricity. The electrode is connected to a source of an electrical charge such that an electrical field gradient is formed in a region of space surrounding the electrode. The electrical field gradient is operable to force the chemical sterilant molecule toward the electrode.
摘要:
Hydrogen peroxide is vaporized (20) and mixed (30) with ammonia gas in a ratio between 1:1 and 1:0.0001. The peroxide and ammonia vapor mixture are conveyed to a treatment area (10) to neutralize V-type, H-type, or G-type chemical agents, pathogens, biotoxins, spores, prions, and the lip-,e. The ammonia provides the primary deactivating agent for G-type agents with the peroxide acting as an accelerator. The peroxide acts as the primary agent for deactivating V-type and H-type agents, pathogens, biotoxins, spores, and prions. The ammonia acts as an accelerator in at least some of these peroxide deactivation reactions.
