The purpose of this project was to determine the suitability of low cost environmental air quality sensors, for detection of pipeline gas quality. In particular, this project examined options for detection and quantification of hydrogen sulfide (H2S), water (H2O), and oxygen (O2). All of the sensors used were based on Synkeras existing anodic aluminum oxide (AAO) platform and detection chemistry. The key challenge of this effort was laboratory based demonstration of the feasibility of detecting these three components in natural gas at pressures exceeding 1 atmosphere
