DETECTION OF STERILISATION VAPOUR CONDENSATION POINT

摘要

The disclosure relates to a method of detecting bacterial kill using a vaporised sterilant comprising the steps of generating a sterilant/water vapour and supplying the vapour to a sealed space to be sterilised. The supply of sterilant vapour is continued to raise the concentration of sterilant in the sealed space, and the concentration of the sterilant in the vapour is monitored to determine when the rate of change of concentration falls to a predetermined minimal level indicating that condensation has occurred resulting in kill of any bacteria present in the space. Supply of sterilant vapour to the space is then terminated.
