自从1963年Kelker开始使用液晶作气相色谱固定液以来,已研究和应用过200多种低分子液晶。用低分子液晶作成的填充柱在不高于180℃的柱温下使用,证明具有很好的选择性和使用寿命;用低分子液晶制成的毛细管柱在较低的温度下使用具有高效、高选择性
Since Kelker began using liquid crystal for GC fixation in 1963, over 200 low-molecular-weight liquid crystals have been studied and applied. Use of low molecular weight liquid crystal made of packed column at a column temperature of not higher than 180 ℃, proved to have good selectivity and service life; made of low molecular liquid crystal capillary column at a lower temperature with high efficiency, High selectivity
