The present review reports, for the first time, various comprehensive two-dimensional gas chromatography (GC×GC) applications for different fossil fuel matrices (crude oil, heavy gas oil (HGO), light and middle distillates, coal and shale oil) for the determination of nitrogen-containing compounds. The focus is on the various types of detectors (universal and specific), and their applicability for the separation and speciation of nitrogen compounds (N-compounds) was evaluated. The capability of GC×GC to provide additional chemically specific information using different detector types, including a flame ionization detector (FID), a nitrogen chemiluminescence detector (NCD), a nitrogen-phosphorus (NPD) detector and detectors in combination with mass spectrometry (MS), is described. The coelutions (detection by MS) for various N-compounds, analytes and components of other classes, such as those that are oxygenates and hydrocarbons, are discussed.
本综述首次报道了各种综合二维气相色谱(GC×GC)在不同化石燃料基质(原油、重质瓦斯油(HGO)、轻质和中间馏分、煤和页岩油)中用于测定含氮化合物的应用。重点是各种类型的检测器(通用和专用),并评估了它们对氮化合物(N 化合物)分离和形态分析的适用性。描述了 GC×GC 使用不同类型的检测器(包括火焰离子化检测器(FID)、氮化学发光检测器(NCD)、氮磷(NPD)检测器和与质谱(MS)结合的检测器)提供额外化学特异性信息的能力。讨论了各种 N 化合物、其他类别的分析物和成分(如含氧化合物和烃类)的共洗脱(通过 MS 检测)。
