Description

Technical Field

[0002] With the rapid development of industries such as pharmaceuticals and biochemicals, liquid chromatography separation technology has been increasingly developed and applied, becoming an important method for separating and purifying complex mixtures. The uniformity and stability of the packing density within the chromatographic column bed are closely related to the sample separation effect. Therefore, the packing of the chromatographic column must meet the requirements of bed continuity, uniformity, stability, and tightness. The dynamic compression packing methods for chromatographic columns mainly include axial compression, radial compression, and circumferential compression. The principle of axial compression technology for packing chromatographic columns is to use a piston to compress the bed. External power drives the piston up and down to pack the column, maintain column pressure, and relieve pressure. The piston is equipped with a sealing ring around the piston, which allows the piston to slide freely up and down while maintaining a high sealing pressure.

The mass of a column head (piston) with a diameter of more than 600mm is usually more than 200kg, and the maintenance work cannot be completed entirely by manpower. Utility Model Content
