Sterilant gas monitoring is the detection of hazardous gases used by health care and other facilities to sterilize medical supplies that cannot be sterilized by heat or steam methods. [1] The current FDA approved sterilant gases are ethylene oxide , [ 2 ] hydrogen peroxide [ 3 ] and ozone . [ 4 ]
Anprolene is a registered trade name for ethylene oxide that belongs to Andersen Sterilizers.. Harold Willids Andersen invented Anprolene in 1967 and used plastic bags and small ampoules, hence, substantially less ethylene oxide (EtO) than traditional chamber type sterilizers which employ tanks of EtO.
Ethylene oxide is a colorless gas at 25 °C (77 °F) and is a mobile liquid at 0 °C (32 °F) – viscosity of liquid ethylene oxide at 0 °C is about 5.5 times lower than that of water. The gas has a characteristic sweet odor of ether, noticeable when its concentration in air exceeds 500 ppm. [ 26 ]
Sterilization can also be achieved using ethylene oxide (ETO) gas. This process was created in the 1950s by the US military [4] and is used on items that cannot withstand the high temperatures of steam sterilization. ETO sterilization takes far longer than steam sterilization and is hazardous to workers, so alternative methods were created in ...

Ethylene oxide treatment is the most common chemical sterilization method, used for approximately 70% of total sterilizations, and for over 50% of all disposable medical devices. [ 26 ] [ 27 ] Ethylene oxide treatment is generally carried out between 30 and 60 °C (86 and 140 °F) with relative humidity above 30% and a gas concentration between ...

An autoclave is a machine used to carry out industrial and scientific processes requiring elevated temperature and pressure in relation to ambient pressure and/or temperature. Autoclaves are used before surgical procedures to perform sterilization and in the chemical industry to cure coatings and vulcanize rubber and for hydrothermal synthesis ...
