Abstract

New restrictions by the Environmental Protection Agency (EPA) are limiting the amount of certain gases released into the atmosphere by industries. These restrictions will have the greatest effect on the automobile and power industry, especially in fossil fuel burning power plants. These industries rely on powerful gas sensors to monitor and control emissions. But in order to meet the demand set by the new standards a new sensor is needed. This new sensor must be capable of withstanding harsh temperatures (In excess of 600°C) and providing a quick response to change in gas environment. We have developed a high throughput cell capable of exposing multiple new sensors to the same gas environment simultaneously. By using a physical deposition chamber we were able to quickly manufacture new sensors to be tested in the cell. Currently we are in the process of validating this high throughput system by testing it using previously studied sensors.
