In order to realize on-site monitoring of mixed gases of volatile organic compounds (VOCs) and fuel cell (FC) gases, we propose a ball surface acoustic wave (SAW) gas chromatograph (GC) that operates at room temperature, using ball SAW sensors and microelectro mechanical systems (MEMS) columns. The ball SAW GC can rapidly analyze mixed gases including wide range of molecular weights by switching two combinations of column sensor pairs from series to parallel. As the component suitable for prtable GC, we developed metal MEMS column to improve the robustness and reduce the cost of previous silicon MEMS columns. A prototype of the ball SAW GC was assembled and the performance was evaluated by the analysis of a model VOC gas and a model town gas. As a result, it was verified that this system can separate and detect each component of these mixed gases. Moreover, we succeeded in fabricating active-carbon-packed metal MEMS column for FC gas including H2. Therefore, the ball SAW GC will realize on-site monitoring of VOC and FC gases to be used at cars, home and smart grids.
