第四原型在距离旋转轴中心15厘米处的横向位置保持一对柱保持器，该旋转轴水平安装在距离设备中心轴线7.6厘米处的旋转框架上。使用短线圈的2.6 mmI.D.PTFE（聚四氟乙烯）管与7.6厘米和24厘米的螺旋直径，固定相的保留测量在10对两相溶剂系统在各种实验条件下。通过选择三个因素的适当组合，即，行星运动方向、首尾洗脱模式和向内向外洗脱模式。极性丁醇溶剂系统在7.6cm螺旋直径的左手线圈中显示出65 - 80%的优异保留
the fourth prototype holds a pair of column holders in the lateral position at 15 cm from the center of the rotary shaft horizontally mounted on the rotary frame at 7.6 cm from the central axis of the apparatus. Using short coils of 2.6 mmI.D.PTFE(polytetrafluoroethylene) tubing with 7.6 cm and 24 cm helical diameters, retention of the stationary phase was measured in ten pairs of two-phase solvent systems under various experimental conditions. Satisfactory retention was obtained by choosing proper combinations of three factors,i.e., the direction of planetary motion, head—tail elution mode, and inward—outward elution mode. The polar butanol solvent systems showed excellent retention from 65 to 80% in the 7.6 cm helical diameter left-handed coil
