用极性固定液涂渍毛细管柱的技术目前正处于发展阶段,所得柱效及热稳定性普遍较低。这主要是由于极性固定液在玻璃和熔融二氧化硅表面不易润湿和极性固定液耐热性差
The technique of coating capillary columns with polar fixatives is currently under development with generally low column efficiency and thermal stability. This is mainly due to the non-wettability of the polar fixing solution on the surface of the glass and the fused silica and the poor heat resistance of the polar fixing solution
