摘要： An electrochemical analysis system includes a chamber (34) that defines a fluid receiving reservoir therein. A working electrode (40), a reference electrode (42), and a counter electrode (44) is mounted to the chamber. An electrochemical analysis circuit (38) applies appropriate voltages to the electrodes and reads appropriate currents from the electrodes to provide an indication of the peroxyacetic acid concentration in a sample. The working electrode includes a glassy carbon rod (60) which is surrounded by a compressible polymeric sleeve (64) and a metal sleeve (66). One end of the metal sleeve is swaged (68) to form a fluid tight compression seal with the insulating sleeve and the glassy carbon rod. An electrically conductive thermal extension joint between the glassy carbon rod and an electrically conductive rod (70) includes a bore (72) in the conductive rod in which the glassy carbon rod is slidably received and a compressed spring (74) in the bore.

摘要： An electrochemical sensor (A, A′) is specific for the detection of peroxyacetic acid in a solution which also contains hydrogen peroxide. A potential is applied between a reference electrode (120, 120′) and a working electrode (118, 118′). A read voltage (FIG. 7) is selectively pulsed across a counter electrode (122, 122′) and the working electrode. The current flowing between the working electrode and the counter electrode is dependent on the peroxyacetic acid concentration in the solution (FIG. 6). By careful selection of the read voltage, the contribution of hydrogen peroxide to the current flow is virtually negligible. The sensor effectively measures peroxyacetic acid concentrations in the range generally employed in sterilization and disinfection baths (100-3000 ppm.).

摘要： A large convoluted space, such as a multi-story concourse of an airport is isolated and a chemical or biological agent in the concourse is deactivated. A plurality of deactivation gas sources (100) introduce a deactivation gas at multiple points along the concourse. Fans (66, 106) circulate the deactivation gas, sensors (110) sense concentrations of the deactivation gas at numerous points around the concourse and exhaust fans (66) exhaust air, spent deactivation gas, and some deactivation gas. A control processor (84) controls the generators, the circulation fans, and the exhaust fans in accordance with the gas concentrations sensed by the sensors to increase and decrease deactivation gas concentration in selected subregions of the concourse by increasing or decreasing generation, increasing or decreasing exhausting, or altering flow patterns among subregions.

摘要： When microbial contamination is introduced into a room (20*) of an enclosure, such as a building, an HVAC system including supply ductwork (16) and a return ductwork (34) is decontaminated with hydrogen peroxide vapor. A decontamination controller (46) operates controllable baffles (22) at outlet registers (20), temporary controllable baffles (44) at inlet registers (30), and a blower system (10) to circulate hydrogen peroxide vapor from hydrogen peroxide vapor generators (42) through the ductwork in both forward and reverse directions. Further, at least portions of the baffles are closed to create dwell times in which the hydrogen peroxide vapor resides in the ductwork with minimal or turbulent flow.

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： 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.

摘要： A BIER vessel evaluates biological indicators for sterilization processes. By flowing gaseous sterilant, such as vaporized hydrogen peroxide, through a chamber (12) before, during, and after introducing the indicators, the indicators are instantaneously exposed to preselected steady state conditions, allowing accurate and reproducible evaluation of the indicator response. A door (32) to an opening (30) in the chamber opens for introducing the indicators to the chamber without appreciably disturbing the steady state conditions therein. After a preselected time, the biological indicators are removed and evaluated for remaining biological activity.
