Abstract

The invention includes a system and a method for maintaining a selected concentration of a sterilant vapor during vapor phase sterilization. The system includes a sterilization chamber with a source of multicomponent vapor containing a sterilant vapor, an electromagnetic radiation source capable of generating radiation at a plurality of wavelengths, a radiation detector for detecting and quantitating the electromagnetic radiation absorbed at the wavelengths, the detector generating absorbance signals proportional to the concentration of the sterilant vapor in the multicomponent vapor, a microprocessor programmed to compare the absorbance signals with reference absorbance signals, to calculate the sterilant vapor concentration therefrom and to generate an output signal, and a controller to receive the output signal and to control addition of the sterilant vapor to the sterilization chamber to maintain a selected concentration of the sterilant vapor in the sterilization chamber during the sterilization process. The method allows sterilization conditions to be optimized to reduce the time required for and to increase the sterilization efficacy of the sterilization procedure.
