ABSTRACT:
A sterilization method is provided which includes the steps of measuring the pressure within a sterilization chamber injecting a sterilant vapor into a flow of carrier gas, introducing the sterilant vapor and carrier gas into and through a sterilization chamber, and adjusting the rate of sterilant vapor injection to reach a pre-determined percentage of saturation limit for the sterilant vapor in the chamber, immediately following the introduction of sterilant vapor and carrier gas into the chamber, in response to the measured pressure. The predetermined saturation limit is selected to optimize the rate of sterilization, while avoiding substantial condensation of the sterilant.
