The U-Pb isotope system, in particular, has become an important tool in isotope geochronology research. These advancements have driven the need to optimize metal isotope purification processes to improve analytical accuracy and efficiency. Building upon previous work, the Metal Stable Isotope Laboratory at the University of Science and Technology of China has established a new V isotope analysis method, improving the separation efficiency and universality of the chemical process while significantly enhancing the measurement accuracy of V isotopes. This demonstrates the importance of optimizing metal isotope purification processes for improving data quality and reducing sample consumption.

[0003] With the increasing demand for metal isotope analysis, the market demand for high-precision and high-efficiency isotope purification technologies is also growing. This prompts researchers to continuously explore and optimize purification processes to meet market demands. Improving reagent purity during chemical processing, avoiding contamination of glassware, reagents, and the environment, and minimizing experimental blanks are all important considerations in optimizing metal isotope purification processes. These factors directly affect the accuracy and reliability of metal isotope analysis. With advancements in multi-sensor inductively coupled plasma mass spectrometry (ICP-MS) and thermal ionization mass spectrometry (TIMS), the requirements for metal isotope purification processes are becoming increasingly stringent to meet the demands of high-precision measurements. Existing isotope purification technologies or devices may suffer from cumbersome and complex purification processes, or imperfections, requiring further improvement. Utility Model Content

[0021] To make the technical problems, solutions, and advantages of this utility model clearer, a detailed description will be provided below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a locking connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] like Figures 1-4 As shown, an embodiment of this utility model provides an isotope purification auxiliary device, including a base 1, a central column 2, a top plate 3, and a clamping plate 4. The base 1 is horizontally positioned (relative to the working surface), and the central column 2 is vertically positioned relative to the base 1, with its bottom end connected to the base 1, allowing it to rotate relative to the base 1. The top plate 3 and clamping plate 4 are both mounted on the central column 2 and rotate synchronously with it.

[0025] In this embodiment, the top plate 3 is provided with clamping holes 5 for holding the isotope purification column, and the clamping plate is provided with support holes 6 for placing a beaker. The support holes 6 and clamping holes 5 are provided in a one-to-one correspondence, so that during the isotope purification process, the liquid is contained in the beaker below the isotope exchange column. It can be understood that the clamping holes 5 adopt a through-hole form to clamp and fix the isotope purification column (by means of interference fit, etc.), while the support holes 6 adopt a groove form to stably support the beaker and prevent the highly corrosive liquid inside the beaker from tipping over.

[0026] In this embodiment, the top plate 3 and clamping plate 4 rotate synchronously with the central column 2, which facilitates rotating the target isotope purification column to an easily observable and operable position, and ensures that the isotope purification column is always aligned with its corresponding beaker, thereby guaranteeing the smooth progress of the purification process. Based on this, this embodiment employs a fixed arrangement of the top plate 3, clamping plate 4, and central column 2, so that the clamping plate 4 rotates synchronously when the central column 2 rotates relative to the base 1.

[0027] In one specific embodiment of this example, the outer surface of the central column 2 is provided with an external thread 7 along the length direction, and the center of the top plate 3 and the clamping plate 4 is provided with a threaded hole 8, and the threaded hole 8 is provided with an internal thread. The threaded hole 8 cooperates with the external thread 7 of the central column 2 to achieve the purpose of fixing the top plate 3 and the clamping plate 4, and they rotate synchronously with the central column 2.

[0028] Meanwhile, based on the threaded connection, the positions of the top plate 3, clamping plate 4, and central column 2 are all adjustable, and the adjustment is stepless. Position adjustment can adapt to different isotope exchange column purification analyses, improving the flexibility of use, especially compared to using positioning holes. In a preferred embodiment, multiple nuts 9 are also fitted onto the central column 2. The nuts 9 are located on the upper and lower sides of the top plate 3 and clamping plate 4, and are also threaded into the central column 2. Further tightening of the nuts 9 prevents the top plate 3 and clamping plate 4 from rotating relative to the central column 2 and loosening during rotation under load, further improving the reliability of the device.

[0029] In this embodiment, a bearing 10 is provided at the center of the base 1, and the bottom end of the central column 2 is connected to the bearing 10. The bearing 10 provides rotational support to the bottom end of the central column 2, thereby improving the stability of the synchronous rotation of the central column 2, the top plate 3, and the clamping plate 4, especially the stability of rotation after bearing load.

[0030] In this embodiment, the surface of the support hole 6 is frosted to increase the surface roughness, thereby improving the anti-slip effect and allowing the beaker to be placed more firmly in the support hole 6, ensuring the safety of the purification process.

[0031] The apparatus provided in this embodiment can support the purification of all wet metal isotopes, including Li, Mg, Cu, Zn, etc., reducing human error in the analysis process.

[0032] In one specific embodiment of this example, the top plate 3 has 12 clamping holes 5, allowing for the simultaneous purification of 12 sets of isotope exchange columns. Correspondingly, the clamping plate 4 also has 12 support holes 6. The top plate 3 has a radius of 150 mm and a thickness of 10 mm, with the clamping holes 5 having a diameter of 8-10 mm. The clamping plate 4 has a radius of 150 mm and a thickness of 10 mm, with the support holes having a diameter of 20 mm. The central column 2 has a length of 600 mm and a radius of 15 mm.

[0033] In summary, the isotope purification auxiliary device provided in this embodiment, through the arrangement of the central column 2, the top plate 3 and the clamping plate 4, and the support of the bearing 10, allows for manual rotation of the platform of the top plate 3 or the clamping plate 4, and also allows for easy adjustment of the height of the top plate 3 and the clamping plate 4. This flexibly adapts to purification experiments of isotope purification columns of different sizes, and the entire process can be completed in a short time, significantly improving work efficiency. It is applicable to different metal isotope purification processes and has strong versatility.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
