Abstract:
1. A gas-detection system, comprising: a sensor capable of detecting one or more select gas species, the performance of which sensor is degraded by contact with ozone; and a scrubber capable of converting ozone to one or more other substances so as to mitigate degradation of the sensor's performance, the scrubber being positioned along a pathway leading to the sensor such that the scrubber and fluid in gas form traveling the pathway in the direction of the sensor can come into contact, but fluid travel via the pathway is not substantially obstructed, wherein the scrubber comprises a “Y”-shaped insert consisting of three rectangular members joined at a common longitudinal axis and extending along the scrubber, the insert being oriented so that the longitudinal axis is substantially parallel with the direction of the flow of the fluid and wherein said “Y”-shaped insert does not interfere with the flow of the fluid.
