Abstract
A sensor system that monitors agent breakthrough through a vapor barrier and related test process. The system includes a substantially airtight test chamber for retaining the vapor barrier, which may be formed of one or more layers of one or more materials. A sensor element array placed adjacent to the barrier under test includes elements that are sensitive to one or more agents of interest and elements that are insensitive to such agents. The insensitive elements provide a baseline reference signal that is compared to the output signal of the sensitive elements. As the agent contacts the array, the electrical signal output from the sensitive elements changes in comparison to that of the reference elements. The sensor array is sensitive enough to detect low levels of the agent when the agent passes through the barrier. A control system is used to regulate and monitor environmental conditions within the chamber and to process electrical signals from the sensor array.
