In this investigation, the gas chromatographic (GC) analysis of citrus essential oils is carried out in 3.3 min, with a speed gain of almost 14 times in comparison with traditional GC procedures. The fast method that is developed requires the application of severe experimental conditions (accelerated temperature program rates, high inlet pressures, and split ratios) and, thus, the support of adequate instrumentation. The samples investigated can be considered to be rather complex and, although a slight loss in peak resolution is observed, the overall analytical result is excellent. All data obtained are compared with that of a conventional application on the same matrices. This is done in order to evaluate the effectiveness and advantages of fast GC achieved with narrow bore columns.
在本研究中，柑橘类精油的气相色谱（GC）分析在3.3分钟内完成，与传统GC方法相比速度提高了近14倍。所开发的快速方法需要应用严格的实验条件（加速升温程序速率、高进样口压力和分流比），因此需要合适的仪器支持。所研究的样品可被认为相当复杂，尽管观察到峰分辨率略有损失，但总体分析结果良好。将获得的所有数据与在相同基质上的传统应用数据进行比较。这样做是为了评估使用窄径柱实现的快速GC的有效性和优势。
