  • Publication number: 20240033389
    Abstract: The present invention relates to the detection vapor peracetic acid and hydrogen peroxide. It finds particular application in the sensing of vapor peracetic acid and hydrogen peroxide concentrations. The system includes (a) a source of peracetic acid vapor, hydrogen peroxide vapor, water vapor and acetic acid vapor, (b) a light source which is configured to supply light with at least a component in the mid-infrared range, and (c) a detector which is configured to individually detect mid-infrared range light in (i) a first mid-infrared spectrum absorbed by the peracetic acid vapor and not absorbed by the hydrogen peroxide vapor, the acetic acid vapor or the water vapor, and (ii) a second mid-infrared spectrum absorbed by the peracetic acid vapor and the hydrogen peroxide vapor.

  • Publication number: 20220195334
    Abstract: This disclosure describes a composition which can provide real-time feedback during medical device cleaning or reprocessing. The composition can be used to monitor the amount of biological material cleaned from medical devices and to determine when cleaning is complete. The disclosure also relates to a method of cleaning, or assessing the cleanliness of, a medical device such as an endoscope. Cleanliness can be assessed by contacting the medical device with the composition, shining an excitation light on the composition, and measuring intensity of resulting fluorescence over time.

  • Publication number: 20200375691
    Abstract: Systems and methods are disclosed for forming a vaporized peracetic acid, with sterilization taking place at ambient temperature. In particular, the disclosed peracetic bubbler technology may achieve sustained peracid acid concentrations. This bubbler and vaporization technology requires no further mechanical assistance, such as pumps, to move peracetic acid vapor into the interior components of an endoscope or any other medical device or medical appliance.
