EO Concentration Commonly 400 and 700 mg/l As EO concentration increases at a given temp and RH, –microbial inactivation (kill) rate increases Killing concentration required at the site where the microbes (BI’s) are located Water Vapor (Humidity) Required for EO to react with the critical cell molecules • Generally measured as Relative Humidity Temperature Kill Read more about Four Basic Factors to Microbial Kill[…]
