Multi-channel SAW chemical sensor is first used to analytical system for organic gas detection. SAW sensors are easy to show a high frequency property, and can become multi-channel devices on a substrate. The features improve a sensor sensitivity and enables integration of sensor. In this paper, we propose a new chemical sensor system using multi-channel SAW devices. A four channel SAW delay line was designed and fabricated on one piezoelectric substrate. Each channel was coated by a different selective organic film and the output of the each channel was used to make a response pattern. The each response to odorant solvents showed the different analyte specific patterns.
