综述和评论了液晶用作气相色谱（ＧＣ）固定液的现状及发展前景。目前，向列相、近晶相、胆甾相液晶分别按其各自的保留机理用于各种位置异构体的分离，以其高效、高选择性而优于常规固定液。继续将液晶冠醚用作ＧＣ固定液的研究并探索手性液晶对于对映异构体的分离是今后液晶固定液研究工作的主要方向。
The status and development prospects of liquid crystal for gas chromatography (GC) fixative are summarized and reviewed. At present, the nematic, smectic and cholesteric liquid crystals are respectively used for the separation of various positional isomers according to their respective retention mechanisms, and are superior to the conventional fixing liquid in terms of high efficiency and high selectivity. Continuing to use liquid crystal crown ether as a GC fixative and exploring the separation of enantiomers by chiral liquid crystals are the main directions for the future study of liquid crystal fixatives.
