This study was designed to analyse a few of aroma gas quantitatively. For three essential oil gas such as sweetorange, roman chamomile, and jasmine, the composition were analysed by GC/MS, the odor intensity andconcentrations were quantified by olfactory method, and the response patterns were analysed by MOS(metaloxide sensors) system. As the results, more than 70% component of sweet orange was limonene as a majorcomposition. While jasmine was composed with various components of relatively high molecular weight andhydrophobicity, roman chamomile was composed with lower molecular weight of substances. The results ofodor intensity and concentrations of aroma gas appeared to have clear linear relations with the outputs of thegas sensor system, showing the possibility of quantifying the concentration of essential oil gas with gas sensorsystem. In addition, patterns of essential oil gas could be classified according with the difference of sensitivityof gas sensors.
