<P>PROBLEM TO BE SOLVED: To provide a system for a real-time monitoring and an electronic control of the concentration of chemical sterilant or disinfectant. <P>SOLUTION: A semiconductor sensing element is mounted in a sterilization chamber 1. A receiving unit monitors the solid-state sensing element and stores a baseline electrical characteristic value corresponding to a baseline concentration of the sterilant at a first set of values of environmental parameters, for example, temperature, pressure, relative humidity, air-flow velocity, an oxidizing substance concentration, and combinations of these. The receiving unit compares changes in the real-time semiconductor sensing element electrical characteristic with the baseline characteristic value to provide a real-time indication of sterilant concentration. A sterilizer control section 12 controls a concentration of sterilant in the sterilization chamber and other sterilization system parameters in accordance with the real-time sterilant concentration from the receiving unit. <P>COPYRIGHT: (C)2008,JPO&INPIT |
