  • Patent number: 8163235
    Abstract: 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.

    Abstract: A reel-to-reel aerosol collection and storage system for capturing and storing a plurality of separate samples of aerosol particles using electrostatic precipitation technology for collecting such particles onto a tape mechanism for analysis at a future time. The particles are collected onto a region of the collection tape for a defined period of time and then that portion of the collection tape is advanced out of the collection zone and manipulated so as to form sealed pouches or pockets which can be either severed from the collection tape for individual storage in a temperature controlled storage container, or which can be stored on a take-up reel in a temperature controlled environment. The collected aerosol particles are stored with a buffer fluid to preserve and maintain the viability of the collected particles for future extraction and analysis. Several embodiments for forming sealed pouches or pockets and methods of storing the collected particles are disclosed.
