在本研究中，使用石英谐振器气体传感器来区分具有非常相似香气的光学异构体。已经发现，当磷脂膜、气相色谱固定相材料和纤维素膜用作石英谐振器气体传感器上的涂膜材料时，右旋光学异构体（d-异构体）和左旋光学异构体（l-异构体）的传感器输出之间的差异可以忽略不计。相反，当使用典型的手性化合物如环糊精作为膜材料时，可以成功地区分光学异构体。
In the present study, the discrimination of optical isomers with closely similar aromas has been performed using quartz-resonator gas sensors. It has been found that the difference between the sensor outputs of a dextrorotatory optical isomer (d-isomer) and of a laevorotatory one (l-isomer) is negligibly small when phospholipid films, gas-chromatographic stationary-phase materials and cellulosic films are used for the coating-film materials on quartz-resonator gas sensors. In contrast, when a typical chiral compound such as cyclodextrin is used as the film material, the optical isomers can be successfully discriminated.
