  • Patent number: 6852277
    Abstract: A sterilization system and method applies low frequency power to a plasma within a vacuum chamber to remove gas or vapor species from an article. The sterilization system includes a switching module adapted to pulsate the low frequency power applied to the plasma and a low frequency power feedback control system for controllably adjusting the low frequency power applied to the plasma. A power monitor is adapted to produce a first signal indicative of the low frequency power applied to the plasma within the vacuum chamber. A power control module is adapted to produce a second signal in response to the first signal from the power monitor, and a power controller is adapted to adjust, in response to the second signal, the low frequency power applied to the plasma to maintain a substantially stable average low frequency power applied to the plasma while the article is being processed.

  • Patent number: 6746647
    Abstract: A method is provided for rapidly determining whether a load of equipment to be sterilized in a sterilization chamber absorbs, adsorbs, condenses, or decomposes significant amounts of germicide vapor or gas, such as hydrogen peroxide. The initial slope of the curve of a plot of ln(c/c0) versus time is determined, where c is the concentration of hydrogen peroxide and c0 is the maximum concentration of hydrogen peroxide. The initial slope is determined in the first 100 seconds after the maximum in the concentration of hydrogen peroxide. If the initial slope is approximately 0.016 sec−1 or less, the load is acceptable. If the initial slope is significantly steeper than 0.016 sec−1, the load absorbs, adsorbs, condenses, or decomposes significant amounts of hydrogen peroxide. If the slope of the curve is steep, the system can abort the sterilization run before significant amounts of hydrogen peroxide have been absorbed, adsorbed, or condensed.

  • Patent number: 6746652
    Abstract: Apparatus and method for producing at high efficiency vaporization a precisely controllable, continuously adjustable gas-phase flow of a vaporizable liquid (e.g., hydrogen peroxide) in a carrier gas (e.g., air) are disclosed. The gas-phase product flow can be substantially continuous, low-temperature, unsaturated with respect to the vaporized vaporizable liquid, and of substantially constant vaporized vaporizable liquid concentration as a function of time. Fine particles of the vaporizable liquid are produced and introduced into the flow of carrier gas/vapor in a vaporization plenum with a sufficient flow of carrier gas/vapor to provide a curtain of carrier gas/vapor between substantially all of the fine particles of vaporizable liquid and the inner surface of the vaporization plenum.
