The toroidal coil using an equilateral triangular core and zigzag pattern column have improved both retention of the stationary phase and peak resolution of the conventional toroidal coil in centrifugal counter-current chromatography. To further improve the retention of stationary phase and peak resolution, a novel saw tooth column was designed and the performance of the system was evaluated at various flow rates. The results indicated that both retention of the stationary phase and peak resolution were improved as the flow rate was decreased and at a flow rate of 0.005 mL/min the resolution is remarkably increased. Modification of the tubing called flat-twisted tubing further improved the peak resolution without increasing the column pressure. With decreased column length at a capacity of about 0.2 mL, resolution of the saw tooth column was 1.02.

离心逆流色谱的新颖设计：III。锯齿柱


采用等边三角形芯和锯齿形柱的环形线圈提高了离心逆流色谱中传统环形线圈的固定相保留和峰分辨率。为了进一步提高固定相的保留和峰分辨率，设计了一种新型锯齿柱，并在不同流速下评估了系统的性能。结果表明，随着流速的降低，固定相的保留和峰分辨率均得到改善，并且在0.005 mL/min的流速下，分辨率显着提高。对称为平扭管的管道的改进进一步提高了峰分辨率，而无需增加柱压。随着容量约 0.2 mL 的柱长度减小，锯齿柱的分辨率为 1.02。
