Herein we report the first example of exploring bio-based materials, palm fibers (PFs), as a stationary phase for capillary gas chromatographic separations. The PFs capillary column was fabricated by the sol-gel coating method and showed a weak polar nature and high column efficiency over 4699 plates per m for -dodecane, naphthalene and -octanol. Importantly, the column exhibited high selectivity and resolving capability for more than a dozen mixtures covering a wide-ranging variety of analytes and isomers. In addition, it was applied for the determination of isomer impurities in real samples, proving its good potential for practical gas chromatographic analysis.
在此，我们报告了首个探索基于生物的材料——棕榈纤维（PFs）作为毛细管气相色谱分离固定相的实例。通过溶胶 - 凝胶涂层法制备了PFs毛细管柱，该柱显示出弱极性性质，对正十二烷、萘和正辛醇的柱效超过每米4699理论塔板数。重要的是，该柱对涵盖多种分析物和异构体的十几种混合物表现出高选择性和分离能力。此外，它还被应用于实际样品中异构体杂质的测定，证明了其在实际气相色谱分析中的良好潜力。
