This work compares the composition at different temperatures of gaseous phase of bergamot essential oil at equilibrium with the liquid phase. A new GC-MS methodology to determine quantitatively the volatile aroma compounds was developed. The adopted methodology involved the direct injection of headspace gas into injection port of GC-MS system and of known amounts of the corresponding authentic volatile compounds. The methodology was validated. This study showed that gaseous phase composition is different from that of the liquid phase at equilibrium with it.
这项工作比较了佛手柑精油在不同温度下与液相达到平衡时气相的组成。开发了一种用于定量测定挥发性香气化合物的新气相色谱 - 质谱（GC - MS）方法。所采用的方法包括将顶空气体直接注入GC - MS系统的进样口以及注入已知量的相应挥发性标准化合物。该方法经过了验证。本研究表明，气相组成与与之平衡的液相组成不同。
