摘　　要：本文研究混合液晶作气相色谱固定液的色谱行为,比较了混合液晶和单个液晶的温度特性、过冷状态稳定性;测定了一些液晶及其混合物的相常数,并对一些难分离物质和复杂天然产物进行了分离和鉴定。实验证明,用混合液晶作固定液常较单种液晶优越。In present paper, chromatographic behavior of mixed liquid crystals used as stationary phases in GC has been studied. Their dependency on the temperature, the stability of supercooled state were compared with those of the homo-liquid crystals. The phase constants, relative polarity of some liquid crystals and their mixtures were determined. In general, the resolving powers of mixed liquid crystals are better than that of corresponding homo-liquid crystals.On the packed and the glass capillary columns coated with a mixed liquid crystal, some natural essential oil and synthetic mixtures have been separated.
