Technical Field

[0001] The utility model relates to the technical field of chromatographic separation, and specifically discloses a chromatographic separation device. Background Art

[0002] Chromatographic separation technology utilizes the different distribution coefficients of different substances in a system consisting of a stationary phase and a mobile phase. When the two phases are in relative motion, these substances move with the mobile phase and are repeatedly distributed between the two phases, thereby achieving separation. Chromatographic separation equipment is a key device for chromatographic separation and analysis and is widely used in various fields such as chemistry, biology, environment, and food. The Sequential Simulated Moving Bed (SSMB) chromatographic separation equipment is an advanced separation device with a complex structure and high technical content, integrating process, equipment, electrical equipment, and automatic control technologies.

[0003] When developing chromatographic separation technology, laboratory chromatographic separation equipment is essential. Currently, chromatographic separation equipment on the market suffers from issues such as being too small or too large. Equipment that is too small can result in experimental parameters that are inconsistent with industrial standards, while equipment that is too large requires a power distribution cabinet to maintain a stable power supply, making it inconvenient to transport and move. Furthermore, the weight of the various added materials and the generated materials must be weighed to promptly assess the test results. Consequently, when transporting chromatographic separation equipment between different test sites or factories, additional accessories such as scales, containers, valves, and pipelines are required, increasing labor costs and making transportation more difficult.
