Ultrafast gas chromatography (UFGC) using a moderately polar column was compared to traditional gas chromatography (GC) for evaluation of biodiesel-diesel blended fuels. Several biodiesel feedstocks (soybean, tallow, canola, palm, camelina) and concentrations (1-20%) were evaluated, with specific attention to the separation of fatty acid methyl esters (FAMEs) from the biodiesel component. UFGC is compared to traditional GC using a similar column chemistry. Principal component analysis (PCA) is performed to identify clustering based on feedstock and concentration. UFGC proves an effective and fast technique, comparable to traditional GC, for the analysis of biodiesel-diesel blended fuels.
使用中等极性柱的超快速气相色谱法（UFGC）与传统气相色谱法（GC）进行了比较，以评估生物柴油-柴油混合燃料。评估了几种生物柴油原料（大豆、牛脂、油菜籽、棕榈、荠蓝）和浓度（1-20%），特别关注生物柴油成分中脂肪酸甲酯（FAME）的分离。UFGC 与使用类似柱化学的传统 GC 进行了比较。进行主成分分析（PCA）以根据原料和浓度识别聚类。UFGC 被证明是一种有效且快速的技术，与传统 GC 相比，可用于分析生物柴油-柴油混合燃料。
