Spring chromatography columnUsually, built-in dynamic axial compression technology is used, which drives the piston to always be connected to the column bed through a spring device inside the column. When the packing of the column bed is rearranged due to the passage of samples and mobile phases, and the volume decreases, the spring will push the piston to compensate for the vacancies generated, continuously providing constant pressure to the column bed, thereby eliminating column dead volume, increasing peak symmetry, and improving column efficiency and chromatographic column life.

　　Spring chromatography columnAdvantages:

Convenient column loading: Short column loading time, no need for secondary disassembly and assembly, avoiding the impact of column bed rebound on column efficiency during traditional chromatography column disassembly and assembly. The loading process is simple and easy to learn, and ordinary users can also master it well.

Stable column efficiency: The piston head is always in contact with the column bed and maintains the column loading pressure, which can effectively prevent the collapse of the column bed, maintain the long-term stability of column efficiency and peak symmetry, and even after thousands of injections and long-term operation, the performance is still reliable.

Wide applicability: Springs with different elasticity coefficients can be selected according to needs, suitable for various fillers such as silicone or polymer media with a diameter of 5 μ m or more, and can also meet temperature control requirements through built-in water bath clamps. In addition, some spring chromatography columns do not use electrical components and can be used in explosion-proof areas.

Application Scenario:

High pressure preparative chromatography: suitable for large-scale sample purification, solving the problem of short lifespan caused by column bed collapse in traditional high-pressure columns.

Industrial Purification and Preparation: Used in the pharmaceutical, biotechnology, chemical, and other fields for the purification of intermediates or final products, supporting continuous production processes.

Research and Teaching: Used by universities and research institutes for method development, packing material screening, or chromatographic column performance research, supporting rapid testing of various packing systems. Simplify the column installation process, lower the operating threshold, and make it suitable for non professionals to use.
