ABSTRACT:
A chemical concentration detecting system for determining the relative concentration of a chemical component in a gas mixture. The gas mixture may include chemical components that are antimicrobial chemicals, as well as chemical components that are base chemicals, acting as a diluent for the antimicrobial chemical, or as a vehicle or carrier for the antimicrobial chemical. A capacitor is exposed to the gas mixture, wherein the gas mixture acts as a dielectric 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 capacitance is used to determine the relative concentration levels of the chemical components in the gas mixture.
