Abstract
The toroidal column using a zigzag pattern has been improved in both retention of the stationary phase and peak resolution. To further improve the retention of stationary phase and peak resolution, a series of novel geometric designs of tubing (plain, mid-clamping, flattened and flat-twisted tubing) was evaluated their performance in CCC. The results showed that the tubing which was flattened vertically against centrifugal force (vert-flattened tubing) produced the best peak resolution among them. Using vert-flattened tubing a series of experiments was performed to study the effects of column capacity and sample size. The results indicated that a 0.25 ml capacity column is ideal for analysis of small amount samples.
摘要
采用之字形图案的环形柱在固定相保留和峰分辨率方面均有改进。为了进一步提高固定相保留和峰分辨率，对一系列新型管材几何设计（普通管材、中间夹紧管材、扁平管材和扁平扭曲管材）在CCC中的性能进行了评估。结果表明，垂直于离心力方向压扁的管材（垂直压扁管材）在这些管材中产生了最佳的峰分辨率。使用垂直压扁管材进行了一系列实验以研究柱容量和样品量的影响。结果表明，0.25 ml容量的柱对于少量样品的分析是理想的。
