把具有适当相变温度的液晶化合物用作色谱固定液,可以有效地分离近沸点的二元取代苯异构体和多环芳烃异构体等难分离混合物,前人在这方面已经作了许多工作。但是,一个至今尚未解决的问题是,由于液晶本身的固有特性,制备性能良好的毛细管柱比较困难,本文为解决这一问题进行了初步尝试。 The use of liquid crystal compounds with suitable phase transition temperatures as chromatographic fixatives can effectively separate near-boiling point, such as binary substituted benzene isomers and polycyclic aromatic hydrocarbon isomers and the like, and many prior art have been made in this regard jobs. However, a problem that has not been solved so far is that due to the inherent characteristics of the liquid crystal itself, it is more difficult to prepare a good capillary column. This paper attempts to solve this problem.
