5.4.3 Study of Odor Preconcentrator Using SAW Device

Yasufumi Yokoshiki & Takamichi Kakamoto
A new type preconcentrator was realized by using a SAW device and peltier devices. First, the odor is delivered to preconcentrator, in which the peltier device cools the surface of SAW device to accumulate the odor. Then the odor is atomized by acoustic streaming using the SAW device. As a result, we obtained much higher response to 1- nonanol, one of low-volatile compounds, because of preconcentrator effect.
