Thin layer chromatography can quickly and accurately separate a certain type of mixture and conduct qualitative and quantitative analysis of a certain component therein. It is often used for substance identification, impurity inspection or content determination, etc.

[0003] Commonly used thin layer chromatography devices include polymer chromatography plates and chromatography cylinders. During the experiment, the prepared developing agent is first injected into the chromatography cylinder, and the cylinder cover is closed. After the atmosphere in the cylinder is saturated, the experimenter opens the cylinder cover, uses tweezers to pick up the spotted thin layer chromatography plate, and puts it into the developing cylinder. The lower end of the chromatography plate is immersed in the developing agent, and its upper end is against the wall of the developing cylinder. The cylinder cover is immediately closed. After the development is completed, the cylinder cover is opened, and the chromatography plate is quickly picked up with tweezers and blown dry with a hair dryer, and then analysis and detection can be carried out. In the existing thin layer chromatography process, limited by the length of the thin layer plate and the volume of the chromatography cylinder, the thin layer plate can only maintain a relatively fixed tilt angle, and a small-sized thin layer plate is prone to tipping over, resulting in failure and inconvenience in the chromatography experiment operation.
