Abstract
This invention relates to a system for mitigating the deleterious effect on a gas-detection sensor of exposure to ozone, which system comprises 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 absorbing ozone or otherwise converting ozone to one or more other substances so as to mitigate degradation of the sensor's performance; and a method for mitigating such deleterious effect as well.
