Abstract
An apparatus for testing peroxide concentration in a gaseous sterilant. A preferred embodiment of the apparatus includes a condenser for condensing the gaseous sterilant into a liquid condensate; an aliquot collector of predetermined volume to receive the condensate; a reaction chamber containing a catalyst for dissociating the peroxide; and a pressure monitor for detecting pressure changes in the reaction chamber as a function of time. The pressure monitor of this apparatus is capable of detecting a threshold pressure and an upper pressure and it includes a timer to measure time change between detection of the threshold pressure and the upper pressure.
