Abstract The toroidal coil using an equilateral triangular core has improved both retention of the stationary phase and peak resolution of the conventional toroidal coil in centrifugal countercurrent chromatography. To further improve the retention of stationary phase and peak resolution, a novel zigzag toroidal coil was designed and the performance of the system was evaluated at various flow rates. The results indicated that both retention of stationary phase and peak resolution were improved as the flow rate was decreased. Modification of the tubing by pressing at given intervals with a pair of pliers improved the peak resolution without increasing the column pressure. All these separations were performed under low column pressure indicating the separation can be further improved by increasing the column length and/or revolution speed without damaging the separation column.

离心逆流色谱的新设计：I. 之字形环形柱

摘要 采用等边三角形芯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率和峰分辨率。为了进一步提高固定相的保留率和峰分辨率，设计了一种新型的锯齿形环形线圈，并在各种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。通过用一对钳子以给定间隔按压来改进管子，在不增加柱压的情况下提高了峰分辨率。
