Description

Technical Field

[0002] Thin-layer chromatography is widely used in the Pharmacopoeia of the People's Republic of China, especially in identification. Color development is the final and crucial step. The quality and uniformity of color development will affect the final interpretation and analysis.

[0003] In existing technology, the air inlet pipe at one end of the colorimetric spray bottle is connected to a single-ball bearing, and air is supplied by squeezing the ball bearing. However, this method has the following drawbacks:

[0005] 2. Uneven spraying of the developer from the spray bottle due to differences in individual pressure;

[0007] Therefore, we propose an auxiliary device for connecting a thin-layer colorimetric device. Utility Model Content

One end of both the exhaust one-way valve 15 and the air inlet one-way valve 16 extends into the bottom of the inner cavity of the hollow column 8.

[0029] The hydraulic rods 7, fixing blocks 12, second guide rings 13, and second guide rods 14 are all in two sets. The two sets of hydraulic rods 7 are fixedly installed between the left and right ends of the upper outer surface of the substrate 5 and the left and right ends of the lower outer surface of the top plate 6. The hollow column 8 is fixedly installed in the middle of the upper outer surface of the substrate 5. The first guide rod 10 is fixedly installed in the middle of the lower outer surface of the top plate 6. The first guide ring 9 is fixedly installed in the middle of the upper outer surface of the hollow column 8, and the inner cavity of the first guide ring 9 communicates with the inner cavity of the hollow column 8. The lower end of the first guide rod 10 penetrates the first guide ring 9 and extends into the interior of the hollow column 8. The outer wall of the first guide rod 10 and the first guide ring 9 are slidably connected. The fixing disc 17, rubber sleeve 18, and limiting disc 19 are all located inside the hollow column 8, providing a limiting effect. There are two sets of discs 19. The two sets of limiting discs 19 are fixedly installed on the outer walls of the upper and lower ends of the fixed disc 17. The middle part of the upper outer surface of the fixed disc 17 is fixedly connected to the lower outer surface of the first guide rod 10. The rubber sleeve 18 is installed on the outer wall of the fixed disc 17 and is located between the two sets of limiting discs 19.

[0030] It should be noted that this utility model is an auxiliary device for connecting a thin-layer color developing device. The color developing spray bottle 1 and the air supply structure 2 described herein are both existing technologies and can be effectively understood by those skilled in the art. Specific details will not be elaborated further. The air guide pipe 4 is connected between the exhaust one-way valve 15 and the air inlet pipe 3. When air needs to be supplied to the color developing spray bottle 1, the operation of the hydraulic rod 7 drives the top plate 6 to descend at a uniform speed. The top plate 6 drives the first guide rod 10 to descend along the first guide ring 9. The first guide rod 10 drives the fixed disc 17 to move inside the hollow column 8. As the column descends, the gas inside the hollow column 8 is forced out through the exhaust check valve 15 and then sent into the interior of the color developing spray bottle 1 through the air guide pipe 4 and the air inlet pipe 3. The top plate 6 drives the second guide rod 14 to slide along the second guide ring 13 to improve the stability of the lifting and lowering. When the hydraulic rod 7 drives the top plate 6 and the first guide rod 10 to reset, outside air enters the interior of the hollow column 8 through the air inlet check valve 16 to facilitate the next set of air supply work. The rubber sleeve 18 improves the sealing performance, and the limit plate 19 facilitates the limiting of the rubber sleeve 18.
