This work presents the first example of the utilization of -butyl(tetradecyloxy)calix[6]arene (C6A-C10) as a stationary phase for capillary gas chromatographic (GC) separation. The statically coated C6A-C10 column showed a column efficiency of 3293 plates per m and had a nonpolar nature. Its selectivity and retention behaviour were investigated using a number of mixtures of diverse analytes and their isomers. As a result, the C6A-C10 column exhibited high resolving capability for aliphatic and aromatic analytes from apolar to polar nature, especially for positional, structural and -/-isomers. Moreover, the C6A-C10 column showed thermal stability up to 240 °C. In addition, it was applied for the determination of isomer impurities in real samples, proving its good potential for practical GC analysis.
这项工作展示了首次将丁基(十四烷氧基)杯[6]芳烃(C6A-C10)用作毛细管气相色谱(GC)分离固定相的实例。静态涂覆的C6A-C10柱每米的柱效为3293塔板,具有非极性性质。使用多种不同分析物及其异构体的混合物研究了其选择性和保留行为。结果,C6A-C10柱对从非极性到极性的脂肪族和芳香族分析物表现出高分离能力,特别是对于位置异构体、结构异构体和α/β异构体。此外,C6A-C10柱在高达240℃时表现出热稳定性。此外,它被用于实际样品中异构体杂质的测定,证明了其在实际GC分析中的良好潜力。
