Color developing device for thin-layer chromatography

The utility model relates to a color developing device for thin-layer chromatographic analysis, which comprises a box body, two opposite side walls of the box body are respectively provided with an opening, and a door is arranged at the opening; the sliding table is arranged in the box body and is used for bearing the thin-layer chromatographic plate; the linear driving mechanism is used for driving the sliding table to reciprocate between the two side walls; and the spraying mechanism is arranged above the sliding table and is used for spraying a color developing agent onto the thin-layer chromatographic plate in the process that the thin-layer chromatographic plate moves along with the sliding table. The color developing device for thin-layer chromatographic analysis is convenient to use, the color developing treatment efficiency of a thin-layer chromatographic plate can be improved, the color developing uniformity and stability are improved, the randomness is reduced, and the reproducibility is improved.
