摘要:【中文】本发明公开了一种细内径毛细管液相色谱柱的填充方法及匀浆罐,采用与填料密度接近的匀浆溶剂在控制填充流速条件下缓慢填充,使填料在色谱柱内规则排布,提高柱效。提出的匀浆罐的圆锥形出料端由高分子材料制成,使填料装填过程中填料颗粒只与高分子材料摩擦碰撞,加之填充流速较低,两个因素结合可以大幅减缓填料装填过程中与变径通道的冲击力。所填毛细管液相色谱柱不仅具有高柱效,而且填料具有低的破碎率,因此惰性更好。可用于药物、蛋白质、激素类组分的高效分离。 【EN】The invention discloses a filling method and a homogenate tank of a capillary liquid chromatographic column with a small inner diameter. The conical discharge end of the proposed homogenate tank is made of high polymer materials, so that filler particles only collide with the high polymer materials in a friction mode in the filling process of the filler, the filling flow rate is low, and the impact force between the filler particles and the diameter-variable channel in the filling process can be greatly reduced by combining the two factors. The capillary liquid chromatographic column has high column efficiency, and the stuffing has low breaking rate and thus high inertness. Can be used for high-efficiency separation of medicine, protein and hormone components.
