Abstract
Methods and apparatus for the timely determination of potentially harmful biocidal gas leakage from a pressurized chamber during sterilizing operations are disclosed. Biocidal gas make-up values are monitored during the sterilizing phase to provide prompt warning of biocidal gas leakage. In one embodiment, the timing of preselected pressure increment gas make-up charges are measured and compared to minimum acceptable gas make-up charge times. In addition, absorption of biocidal gas by the load can be compensated for in sterilizing operations where load absorption is a significant factor. Also, provision is made for predicting gas absorption by the load from steam absorption data obtained during pressure-controlled conditioning cycles.
