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