Abstract: 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.

Abstract: A method and apparatus for formulating and controlling concentrations of deactivating chemicals in a solution inside a chamber. The solution may include chemical components that are deactivating chemicals, as well as chemical components that are base chemicals, acting as a diluent for a deactivating chemical, or as a vehicle or carrier for a deactivating chemical. A capacitor is exposed to the solution, wherein the solution 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 electrical properties of the capacitor can be used to determine the concentration levels of multiple chemical components in the solution.

Abstract: A method and apparatus for measuring the concentration of hydrogen peroxide in a liquid or gaseous fluid. A capacitor is exposed to the fluid, wherein the fluid acts as the dielectric between the conductors of the capacitor. The permittivity and dielectric constant associated with the fluid is affected by the relative concentrations of the chemical components comprising the fluid. A measurement of the capacitance is used to determine the relative concentration levels of the chemical components in the fluid. In an alternative embodiment, a resistor, and associated resistance values, are used to determine the concentration of hydrogen peroxide in a liquid or gaseous fluid.

Abstract: An induction coil (36) generates a magnetic field which induces current in an induction vessel (28). The induction vessel is heated by the current and supplies the heat to a passage (34) within the vessel. A liquid to be vaporized, such as water or hydrogen peroxide solution, is supplied to the passage where it is converted to vapor. The vapor is supplied to a defined area, such as a chamber (14) of a steam or vapor hydrogen peroxide sterilizer (10), where items are microbially decontaminated by the vapor.
