Description

Technical Field

[0001] This utility model relates to the field of chromatography analyzer technology, specifically to a chromatography analyzer instrument. Background Technology

[0002] Chromatographic analysis instruments are technical tools used to separate and detect different substances. They are widely used in various fields. Chromatographic analysis techniques include gas chromatography, liquid chromatography, supercritical fluid chromatography, etc. These techniques utilize the differences in the partition coefficients of the components in the sample between the stationary phase and the mobile phase to separate them.

[0003] Some liquid chromatography (LC) analyzers require sample vials to be placed on top of the instrument during operation, followed by the insertion of connecting tubes. However, in practice, when there are many sample vials on the instrument, there are also many connecting tubes, which can become tangled and damaged. Furthermore, the messy arrangement of the tubes makes it time-consuming for operators to identify which sample vial is connected, making the operation cumbersome. Therefore, a new LC analyzer is proposed to solve these problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a chromatographic analysis instrument that facilitates the fixing of connecting tubes, improves overall aesthetics, and allows for quick identification of which sample vial each connecting tube is connected to. This solves the problem of some liquid chromatography instruments requiring sample vials to be placed on top of the instrument before inserting connecting tubes for analysis. However, in practice, with numerous sample vials on top, the number of connecting tubes increases, potentially leading to entanglement, damage, and a disorganized setup. This also makes it time-consuming and cumbersome for operators to identify which sample vial each tube is connected to.

[0014] Furthermore, there are four support boxes, which are arranged in a rectangular array at the top of the liquid chromatograph. There are multiple connecting cavities, and support legs are fixedly connected to the bottom of the liquid chromatograph.

[0015] Furthermore, the elastic component includes an elastic spring fixedly connected to the inside of the connecting cavity, and the other end of the elastic spring is fixedly connected to an elastic rod extending to the bottom of the support plate. The bottom end of the elastic rod is fixedly connected to the top end of the support plate, and there are multiple elastic rods at the top end of the support plate.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In the embodiments, by Figures 1-4 The present invention discloses a chromatographic analysis instrument, comprising a liquid chromatograph 1, a support box 2 fixedly connected to the top of the liquid chromatograph 1, a support assembly 3 slidably connected to the inner side of the support box 2, a support plate 4 fixedly connected to the top of the support assembly 3, a connecting cavity 5 opened on the inner side of the support plate 4, an elastic assembly 6 fixedly connected to the inner side of the connecting cavity 5, a connecting plate 7 fixedly connected to the bottom end of the elastic assembly 6, an arc plate 8 fixedly connected to the bottom end of the connecting plate 7, and a pushing assembly 9 fixedly connected to the top of the elastic assembly 6.

[0026] The liquid chromatograph 1 is movably connected to a sample vial 10, and a connecting tube 11 is inserted into the top of the sample vial 10. The outer side of the connecting tube 11 is located between the arc plate 8 and the support plate 4.

[0027] The outer side of the connecting pipe 11 is located between the arc plate 8 and the support plate 4, which can effectively prevent the position of the connecting pipe 11 from shifting.

[0028] The support assembly 3 includes a support rod 31 that is slidably connected to the inside of the support box 2. A first adsorption magnet 32 ​​is fixedly connected to the bottom end of the support rod 31, and a second adsorption magnet 33 is fixedly connected to the top end of the liquid chromatograph 1. The outer sides of the first adsorption magnet 32 ​​and the outer sides of the second adsorption magnet 33 are mutually adsorbed.

[0029] The support component 3 can restrict the position of the support plate 4 above the liquid chromatograph 1, thereby facilitating the restriction of the position of the connecting tube 11.

[0030] The liquid chromatograph 1 has four support boxes 2 arranged in a rectangular array at the top of the liquid chromatograph 1. There are multiple connecting cavities 5. Support legs are fixedly connected to the bottom of the liquid chromatograph 1.

[0031] The elastic component 6 includes an elastic spring 61 fixedly connected to the inside of the connecting cavity 5. The other end of the elastic spring 61 is fixedly connected to an elastic rod 62 extending to the bottom of the support plate 4. The bottom end of the elastic rod 62 is fixedly connected to the top end of the support plate 4. There are multiple elastic rods 62 at the top end of the support plate 4.

[0032] The elastic component 6 allows the arc plate 8 to move up and down, thereby allowing the connecting pipe 11 to be confined between the arc plate 8 and the support plate 4.

[0033] The pushing component 9 includes a push rod 91 fixedly connected to the top of the elastic component 6, and a push plate 92 fixedly connected to the top of the push rod 91.

[0034] The push component 9 can push the curved plate 8 up and down.

[0035] Working principle:

[0036] Place the sample vial 10 to be analyzed by chromatography on the top of the liquid chromatograph 1. After placement, insert the support rod 31 into the inside of the support box 2. Then the position of the support plate 4 can be restricted above the liquid chromatograph 1.

[0037] Then, pressing down the ejector plate 92 causes the ejector rod 91 to push the spring rod 62 downward, which in turn causes the arc plate 8 to move downward. Then, the connecting tube 11 is placed under the arc plate 8, and the ejector plate 92 is released, which restricts the position of the connecting tube 11 to the outside of the arc plate 8, thereby effectively preventing the position of the connecting tube 11 from shifting.
