In the field of security and energy exploitation, a wide variety of volatile organic compounds (VOC) are employed. The gas chromatograph (GC) is frequently used for the multiple-gas sensing but is not handy. We have developed the ball surface acoustic wave (SAW) sensor, where SAW with a specific width is naturally collimated and makes multiple roundtrips without diffusing by the diffraction, realizing ultra-high sensitivity. We also succeeded to downsize the gas separation column by micro electro mechanical systems (MEMS) technology. Using them, we have proposed the ball SAW GC. |
