The feasibility of a versatile system for multi-step direct thermal desorption (DTD) coupled to comprehensive gas chromatography (GC x GC) with time-of-flight mass spectrometric (TOF-MS) detection is studied. As an application the system is used for the characterization of fresh versus aged olive oil after treatment at 70, 175, 250 and 600 degrees C.
研究了一种多功能系统的可行性，该系统用于多步直接热脱附（DTD）与全二维气相色谱（GC×GC）联用，并采用飞行时间质谱（TOF-MS）检测。作为应用，该系统用于表征在70、175、250和600摄氏度处理后的新鲜橄榄油与陈化橄榄油。
