Description

Technical Field

[0001] This utility model belongs to the field of chromatography column technology, and more specifically, it relates to a column oven with an automatic chromatography column selection system. Background Technology

[0002] Currently, column ovens generally employ a solid heating method. Solid heating involves machining grooves into an aluminum component to create a groove that conforms to the shape of the column. During use, the column is placed inside the groove, and heat conduction occurs through the contact between the column and the aluminum component, ensuring that the column temperature meets requirements. This method offers high heat transfer efficiency, but it is complex to manufacture, has poor column compatibility, and is prone to localized overheating. This results in rapid heat dissipation, compromising the consistency of the internal temperature. Furthermore, current column ovens do not allow for column switching, and their overall internal structure is not optimized, reducing experimental efficiency.

[0003] Therefore, researching a column oven with a constant temperature and the ability to switch between columns is an urgent problem to be solved. Utility Model Content
