Abstract

This work presents the separation performance of star-poly(ε-caprolactone) (star-PCL) as the stationary phase for capillary gas chromatography (GC). The statically coated star-PCL column showed a column efficiency of 3345 plates per m and moderate polarity. Importantly, the star-PCL column exhibited high selectivity and resolving capability for more than a dozen mixtures covering a wide-ranging variety of analytes and isomers. Among them, the star-PCL column displayed advantageous resolving capability over the commercial DB-1701 column for aromatic amine isomers such as toluidine, chloroaniline and bromoaniline. Moreover, it was applied for the determination of isomer impurities in real samples, showing good potential in GC applications.

摘要

本研究展示了星形聚己内酯（star-PCL）作为毛细管气相色谱（GC）固定相的分离性能。静态涂覆的star-PCL柱每米的柱效为3345塔板，极性适中。重要的是，star-PCL柱对十几种混合物表现出高选择性和分离能力，这些混合物涵盖了广泛的分析物和异构体。其中，star-PCL柱在分离芳香胺异构体（如甲苯胺、氯苯胺和溴苯胺）方面比商用DB-1701柱具有更优异的分离能力。此外，它还被用于实际样品中异构体杂质的测定，在GC应用中显示出良好的潜力。
