    • PROBLEM TO BE SOLVED: To provide a column capable of preventing the leakage of a mobile phase and normally holding a filled state of a particulate separation agent in supercritical fluid choromatography. SOLUTION: In the column used in the supercritical fluid chromatography using a fluid containing a supercritical fluid and a solvent as a mobile phase, the stopper at least on one end side of a hollow pipe 1 is set to a movable stopper 3 and the gap between a movable stopper main body 3a and the hollow pipe 1 is closed by seals 3c and 3d for preventing the leak of the separation agent and the solvent and seals 3e and 3f for preventing the leakage of the supercritical fluid. In a state of depression along the axial direction of the hollow pipe 1, the movable stopper 3 is fixed by a fixing means 4. COPYRIGHT: (C)2006,JPO&NCIPI
    • 要解决的问题:提供一种能够防止流动相泄漏并且通常在超临界流体气相色谱法中保持颗粒分离剂的填充状态的柱。 解决方案:在使用含有超临界流体和溶剂作为流动相的流体的超临界流体色谱柱中使用的柱中,中空管1的至少一端侧的止动件被设定为可移动塞3, 可动止动器主体3a和中空管1之间的间隙由密封件3c和3d封闭,以防止分离剂和溶剂和密封件3e和3f泄漏,以防止超临界流体泄漏。 在中空管1的轴向的凹陷状态下,可动止动件3由固定机构4固定。(C)版权所有(C)2006,JPO&NCIPI
