Methods of Low-Temperature Sterilization: Ozone | Tuttnauer

An ozone sterilizer is able to harness the unique powers of ozone by producing it inside the sterilizer from medical grade oxygen, which is commonly available in hospitals (as explained above, by applying electrical energy to combine O2 with O to form O3). This capability is well-suited for sterilizing delicate medical devices, like endoscopes, that cannot withstand the high heat and humidity ...

7 Techniques For Measurement of Reactive Nitrogen Oxides ...

The chemiluminescence produced by the reaction of ozone with nitric oxide forms the basis for a sensitive and specific ozone detection method. (The reactions of ozone with an unsaturated NMHC such as ethylene also have been used, but they are somewhat less sensitive.) Although chemiluminescence tends to be more complicated than the UV absorption method, it can make fast-response ozone ...
