    • A vaporizer (14) supplies hydrogen peroxide and water vapor to a high level disinfection or sterilization region (20). Mid-infrared light detectors (32) detect light in the mid-infrared range which has traversed a region of the treatment chamber in a first narrow spectrum centered at 8,000 nanometers which is absorbed by the hydrogen peroxide vapor, a second narrow spectrum which is absorbed by the water vapor, and a third spectrum that is absorbed by neither the hydrogen peroxide vapor nor the water vapor. From these measurements, an absorbance or transmittance is determined (40) from which the concentrations of hydrogen peroxide and water vapor are determined (42). Monitored temperature (44) and the determined concentrations are converted into a percent saturation (54). The supply of hydrogen peroxide and water vapor to the chamber is controlled (60) in accordance with the determined percent saturation.

    • A system for sterilizing or microbially deactivating instruments and devices. The system includes a circulation system for circulating a microbial deactivation fluid through a chamber for containing the instruments and devices. The chamber forms a portion of the circulation system. The system further includes a fluid over-flow/make-up air assembly. The fluid over-flow/make-up air assembly includes a manifold having an inner cavity that is in fluid communication with the circulation system, an overflow port in the manifold, and an overflow valve assembly disposed in the manifold allowing fluid flow from the cavity to the overflow port when a pressure in the cavity exceeds a pressure in the overflow port by a predetermined amount. A filter assembly is attached to the manifold. The filter assembly has a filter valve assembly in communication with the cavity. The filter assembly is operable to allow air through the filter assembly into the cavity when the pressure within the cavity is a predetermined amount less than the pressure within the filter assembly.
