Latest Patents
John F Prieve holds a patent for a "Method and apparatus for measuring the concentration of hydrogen peroxide vapor." This invention presents an improved apparatus and method for accurately measuring the concentration of hydrogen peroxide vapor or gas within a sterilization chamber. The measurement is conducted spectrophotometrically in the ultraviolet region between 200 and 400 nm. This method effectively eliminates interference from water vapor, which does not absorb in the ultraviolet region. Additionally, organic compounds that may interfere with the measurement are removed by evacuating the sterilization chamber to low levels prior to the determination of hydrogen peroxide concentration. The system utilizes either a low-pressure mercury vapor lamp or a deuterium lamp with a selective optical filter. A movable gas cell can be employed to measure hydrogen peroxide concentration at various locations within the sterilization chamber. Furthermore, the measurement system can be integrated with a feedback loop to control the concentration of hydrogen peroxide in the chamber.
