Abstract

The invention discloses a chromatographic column temperature control device for a supercritical fluid chromatography system. The device can switch different chromatographic columns online, a preheaterdevice can effectively heat the liquid carbon dioxide to a supercritical state to ensure that the liquid carbon dioxide reach a supercritical state before entering the chromatographic columns, the design of a circulation channel ensures uniform heat in all parts of a column oven, the whole device can be controlled by computer software to control the temperature and select the chromatographic columns, the operation is more convenient, and the automation is high.

Description

technical field [0001] The invention designs a chromatographic column temperature control device for a supercritical fluid chromatographic system, belonging to the field of chromatographic. Background technique [0002] Supercritical fluid chromatography (SFC) is a chromatographic method using supercritical fluid as the mobile phase. The supercritical fluid not only has a viscosity close to gas and a high diffusion coefficient, which is about 10 to 100 times that of liquid, but also has a high density and high density close to liquid. Strong solvency, so SFC has the advantages of both gas chromatography (GC) and high performance liquid chromatography (HPLC); the chromatographic stationary phase used in SFC is similar to that of liquid chromatography, and the mobile phase is generally a mixture of carbon dioxide and organic solvents (methanol, etc.) , it can not only separate thermally unstable, high relative molecular mass, strongly polar or non-volatile compounds that are d...
