The present research is based on the development of an effective, environmentally-friendly and low-cost method for investigation of minor components in vegetable oils, exploiting the advantages of a miniaturized solid-phase extraction (SPE) and the potential of flow modulation (FM) comprehensive two-dimensional gas chromatography (GC×GC), coupled to a mass spectrometer (MS) and a flame ionization detector (FID). The initial sample preparation step was carried out using a miniaturized approach characterized by a SPE process in a Pasteur pipette. Then, the isolated fraction was injected into an FM GC×GC system. Tentative identification was carried out by means of MS spectral information, while quantification was carried out by using the FID data. Four different vegetable oil samples were analyzed using the proposed method, namely an extra virgin olive oil (EVO), a hazelnut oil (HO), a borage oil, and an EVO/HO mixture.
本研究基于开发一种有效、环保且低成本的方法，用于研究植物油中的微量成分，利用微型固相萃取（SPE）的优势和流调制（FM）全二维气相色谱（GC×GC）的潜力，结合质谱仪（MS）和火焰离子化检测器（FID）。初始样品制备步骤采用微型化方法，在巴斯德吸管中进行 SPE 过程。然后，将分离的馏分注入 FM GC×GC 系统。通过 MS 光谱信息进行初步鉴定，而通过 FID 数据进行定量。使用所提出的方法分析了四种不同的植物油样品，即特级初榨橄榄油（EVO）、榛子油（HO）、琉璃苣油和 EVO/HO 混合物。
