TECHNICAL FIELD
[0001] The utility model relates to the field of chromatography platform, especially short chain fatty acid determination with chromatography silica gel plate auxiliary chromatography platform. BACKGROUND
[0002] Short chain fatty acids (SCFAs), including acetic acid, propionic acid and butyric acid, are the main metabolic products of dietary fiber fermentation by intestinal microorganisms. In recent years, more and more studies have shown that SCFAs play an important role in maintaining intestinal health, regulating the immune system, and preventing metabolic diseases. Therefore, rapid and accurate detection of SCFAs content is of great significance for studying its physiological function and developing related disease diagnosis and treatment methods. Among the many detection methods of SCFAs, thin layer chromatography is an important experimental technique for rapid separation and qualitative analysis of small amounts of substances. It is a solid-liquid adsorption chromatography that combines the advantages of column chromatography and paper chromatography. On the one hand, it is suitable for the separation of small amounts of samples; on the other hand, when making thin layer plates, the adsorption layer is thickened and increased, so it can also be used to purify samples. This method is particularly suitable for substances that are less volatile or change easily at high temperatures and cannot be analyzed by gas chromatography. It is an analytical method that uses adsorbents, carriers or other active substances to evenly coat a flat plate, forming a thin layer, and then performing chromatographic separation on the thin layer. Chromatography silica gel plate auxiliary chromatography platform is a device used to assist chromatography plate.
[0003] However, the existing chromatography silica gel plate auxiliary chromatography platform often needs to be irradiated by a UV developing lamp during use, but since the UV developing lamp is usually built-in in a light shield, after long-term use, the local temperature rises easily, affecting the stability of the silica gel plate, and thus accelerating the evaporation of the solvent, thereby affecting the normal implementation of the thin layer chromatography method. UTILITY MODEL CONTENT
[0004] In order to overcome the problem that the existing chromatography silica gel plate auxiliary chromatography platform is affected by the heat accumulated inside the light shield after long-term use, thereby affecting the stability of the silica gel plate and the test data.

The cylindrical light-shielding tube dissipates heat from the ultraviolet developing lamp to prevent heat buildup. At the same time, a servo motor drives the light-shielding tube to swing, thereby improving the cooling efficiency of the cooling fan and significantly extending the service life of the entire chromatography silica gel plate auxiliary chromatography stage.
