摘要： An electrochemical sensor (A, A') is specific for the detection of peracetic 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 to the working electrode and then through the solution to a counter electrode (122, 122'). The current flowing between the working electrode and the counter electrode is dependent on the peracetic 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 peracetic acid concentrations in the range generally employed in sterilization and disinfection baths (100-3000 ppm.).

摘要： A flash vapor generator (10) provides a constant flow of vaporized hydrogen peroxide for rapidly sterilizing a large decontamination tunnel (11) with a high container throughput. The vaporizer includes a heated block which defines an interior bore or bores. The conditions within the decontamination tunnel are carefully monitored to avoid condensation of the vapor while maintaining the vapor as close as possible to the saturation limit.

摘要： A flash vaporizer (34) provides a constant flow of vaporized hydrogen peroxide or other antimicrobial compounds for rapidly sterilizing large enclosures (10), such as rooms or buildings. The vaporizer includes a heated block which defines an interior bore or bores. The flowpath created by the bore or bores may increase in cross sectional area as the hydrogen peroxide passes through the block to accomodate the increase in volume during the conversion from liquid to gas. The vapor is injected into dry air in a duct (23) that circulates it to the large enclosure.

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 sterilization system (14) includes a sensor (10) for detection of a component, such as hydrogen peroxide vapor, in a multi-component vapor, such as a mixture of vapor hydrogen peroxide and water supplied to a chamber (12) of the system. The sensor preferably uses a wavelength range in which hydrogen peroxide strongly absorbs but other components of the vapor, such as water, do not. A suitable wavelength for detection of hydrogen peroxide is from about 7500 to about 8400 nm, since there is little absorption by water in this range. This avoids the need to use complex subtraction procedures normally used to remove the contribution of water from detected absorbance measurements. A control system (16, 30) controls operating conditions of the sterilization system, such as a heater (82), pressure release valves (74), vaporization rate of hydrogen peroxide by a vaporizer (22), and the like to maintain optimum sterilization conditions within the chamber.

摘要： A disinfection/sterilization system includes a chamber (10) through which an antimicrobial solution is circulated. An electrochemical analysis system taps off samples of the circulated antimicrobial solution for analysis. The analysis system includes a chamber (34) that receives the sample. A working electrode (40), a reference electrode (42), and a counter electrode (44) are in electrical contact with the sample. The working electrode includes a brittle material, such as a 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 carbon rod. An electrically conductive thermal extension joint between the carbon rod and an electrically conductive rod (70) includes a bore (72) in the conductive rod in which the carbon rod is slidably received and a compressed spring (74) in the bore. Preferably, an opposite end of the metal sleeve is swaged (78) to form a fluid tight seal with an insulating sleeve (76) and the electrically conductive rod (70).
