[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0034] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0035] With the gradual maturity of laser ablation systems, laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) as a solid direct sampling and micro-area analysis technology is widely used in geology, environment, biology, materials, industrial product testing and other fields. It can analyze major, trace, trace and ultra-trace elements, especially in rare earth elements, PGEs, isotope analysis, etc. It has great advantages. Its application method is that the laser ablation device ablates the solid sample into aerosol through the energy of the laser beam, and transmits it into the inductively coupled plasma mass spectrometer through the carrier gas for elemental analysis.

[0036] Before laser ablation of samples, it is necessary to adjust the working parameters (beam spot diameter, energy density, matrix tube position, etc.) to make the laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) reach a stable state. This process is time-consuming and consumes a lot of gases such as argon and helium. The replacement of each group of samples to be tested greatly reduces the experimental efficiency.

[0037] To solve the above problems, Figure 1-Figure 5 As shown, the present invention provides a card slot type sample plate tray for a sample pool of a NWR laser ablation device, comprising:

[0038] A metal base 2, which is arranged on the top of the metal base 1, and sliding bars 9 are arranged on both sides of the bottom of the metal base 1;

[0039] A plurality of standard sample placement slots 3 are provided. The standard sample placement slots 3 are opened on the metal base 2 and are used to place standard samples.

[0040] The limit groove 4 of the sample to be tested is arranged on the metal base 2. The limit groove 4 of the sample to be tested is located on both sides of the standard sample placement groove 3. The side wall of the limit groove 4 of the sample to be tested is provided with a sample placement plate inlet and outlet hole 7. The limit groove 4 of the sample to be tested is used to place a square sample to be tested;

[0041] A push-pull type sample setting plate 5, which is installed in the sample limit groove 4 through the sample setting plate inlet and outlet hole 7, and a sample setting plate bent handle 8 is provided on the side of the push-pull type sample setting plate 5;

[0042] The sample placement slot 6 is arranged on the push-pull type sample placement plate 5 .

[0043] The present invention can ensure the precise position of the standard sample and the sample to be tested on the metal base 2 by designing the standard sample placement slot 3 and the sample limit slot 4 to be tested, thereby avoiding the position deviation of the sample during the test process, thereby improving the accuracy of the test result. The push-pull type sample plate 5 design allows users to easily place and remove the sample to be tested, and can achieve rapid sample replacement without complicated operations, thereby improving the experimental efficiency. The sample plate entry and exit holes 7 are set on both sides of the sample limit slot 4 to be tested, and are equipped with a push-pull type sample plate 5, so that the card slot type sample plate tray can be suitable for samples of different sizes and shapes to be tested, thereby enhancing its versatility and flexibility. The design of the metal base 2 and the metal matrix 1 makes the entire tray structure stable, able to withstand various forces and vibrations during the test process, and ensure the stability and safety of the sample. The design of the card slot type sample plate tray makes the connection between the various components simple and clear, easy to disassemble and clean, and ensures the cleanliness and hygiene of the experimental environment.

[0044] It can be understood that the setting of the limit groove 4 of the sample to be tested enables the push-pull type sample placing plate 5 to reach the same position each time, thereby avoiding repeated calibration of the sample plate tray and improving the experimental efficiency.

[0045] The technical solution of the present invention shows remarkable beneficial effects in improving the accuracy of sample placement, enhancing the convenience of operation, adapting to different sample requirements, having a stable and reliable structure, and being easy to maintain and clean.

[0046] In some embodiments of the present application, the depth of the standard sample placement groove 3 is greater than the thickness of the standard sample.

[0047] In this embodiment, since the depth of the standard sample placement groove 3 is greater than the thickness of the standard sample, this ensures that the standard sample will not have unnecessary contact or friction with the groove bottom due to insufficient depth during placement, thereby avoiding the measurement error that may be caused by this and improving the accuracy of the experiment. This design allows the use of standard samples of different thicknesses without the need to design a placement groove for each sample of each thickness, greatly enhancing the versatility and flexibility of the equipment and reducing the cost of use. Appropriate depth design can effectively prevent the standard sample from being subjected to unnecessary damage during placement or removal, extend the service life of the standard sample, and reduce the replacement frequency and cost.

[0048] In some embodiments of the present application, the depth of the sample placement groove 6 is less than the thickness of the square sample to be tested.

[0049] In some embodiments of the present application, the depth of the limit groove 4 of the sample to be tested, the depth of the entry and exit hole 7 of the layout plate, and the thickness of the push-pull layout plate 5 decrease in sequence.

[0050] It can be understood that the push-pull type sample plate 5 passes through the sample plate inlet and outlet holes 7 on both sides of the metal base 1 and is pushed and pulled to the square sample limit groove 4 of the metal base 2. The push-pull type sample plate can realize the rapid replacement of samples and improve the experimental efficiency.

[0051] In this embodiment, in order to ensure that the push-pull type lofting plate 5 is placed in the limit groove 4 of the sample to be tested through the lofting plate inlet and outlet hole 7, the depth of the limit groove 4 of the sample to be tested, the depth of the lofting plate inlet and outlet hole 7 and the thickness of the push-pull type lofting plate 5 need to be set to decrease in sequence. The present invention makes the installation and disassembly of the lofting plate more convenient through the push-pull type design, improves the flexibility of operation, and facilitates the user to quickly replace or adjust the lofting plate according to actual needs. The design of the limit groove 4 of the sample to be tested, the lofting plate inlet and outlet hole 7 and the thickness of the push-pull type lofting plate 5 ensures the precise positioning of the lofting plate during the installation process, and effectively prevents the measurement error caused by position deviation. This design makes the structure of the entire device more compact, not only saves space, but also enhances the overall stability, which is conducive to realizing efficient and accurate testing work in a limited space. The push-pull type design simplifies the operation process, reduces unnecessary steps and time consumption, and thus improves the overall test efficiency.

[0052] In some embodiments of the present application, the standard sample placement slot 3 is a circular slot, and there are four standard sample placement slots 3, and the diameters of the standard sample placement slots 3 are 25 mm, 25 mm, 16 mm, and 9 mm, respectively. Multiple standard sample placement slots 3 with different diameters can place samples with different diameter gradients, thereby improving the utilization rate of the sample plate tray.

[0053] In this embodiment, by designing a plurality of standard sample placement slots 3 of different diameters, it is possible to accommodate samples of various diameter gradients, avoiding the limitation of a single-size sample placement slot on sample diversity and tray space, thereby improving the overall utilization of the tray. The diverse design of the standard sample placement slots 3 enables the experimenter to flexibly select and use the appropriate sample size according to different experimental requirements, thereby improving the flexibility and adaptability of the experimental design. There is no need to frequently replace sample plate trays of different sizes, which reduces the operating steps and time costs during the experiment and improves the experimental efficiency. The unified design of the standard sample placement slots 3 is conducive to the standardized management and storage of experimental samples, and is convenient for recording and comparative analysis of experimental results.

[0054] In some embodiments of the present application, the standard sample placement slot 3 is used to place a circular sample to be tested.

[0055] In this embodiment, the samples to be tested include circular samples to be tested and square samples to be tested. The square samples to be tested are placed in the sample placement slot 6 , while the circular samples to be tested can be placed in the standard sample placement slot 3 .

[0056] It is understandable that by designing the standard sample placement slot 3, which is specifically used to place circular samples to be tested, samples of different shapes can be placed in a targeted manner, avoiding placement inconvenience or measurement errors caused by differences in sample shapes. The standard sample placement slot 3 is optimized for circular samples to be tested, which can ensure that the sample remains stable during the measurement process, reduce measurement errors caused by sample movement or tilt, and thus improve measurement accuracy. In the same device, by distinguishing between the standard sample placement slot 3 and the sample placement slot 6, the classified placement of circular and square samples to be tested is achieved, the space utilization of the equipment is optimized, and the entire measurement process is more orderly and efficient. By adding the standard sample placement slot 3, this technical solution enables the device to be applicable to more types of samples to be tested, enhances the applicability and flexibility of the device, and meets the needs of different users and scenarios.

[0057] In some embodiments of the present application, the sample placement groove 6 is a square groove, and the size of the sample limiting groove 4 is 52 mm×27 mm×1.5 mm.

[0058] In this embodiment, the sample placement slot 6 is designed as a square slot, and its size is accurate to 52mm×27mm×1.5mm, which can ensure that the sample to be tested can fit tightly when placed, avoiding movement or shaking of the sample during the test, thereby improving the accuracy and stability of the test. Through the sophisticated design of the sample placement slot, the steps of sample placement can be simplified, and the adjustment time caused by sample size mismatch can be reduced, thereby improving the overall efficiency of the test. Since the sample can remain stable during the test, the influence of external factors on the test results is reduced, so that the performance of the sample to be tested can be more accurately reflected, and the reliability of the test results is enhanced. The design of the square slot makes sample placement more intuitive and convenient, and is also conducive to the cleaning and maintenance of the equipment, reducing the difficulty and cost of operation.

[0059] In some embodiments of the present application, sliding bars 9 are arranged on both sides of the bottom of the metal substrate 1, and the sizes of the sliding bars 9 are 6mm×119mm×5mm and 6mm×126mm×5mm respectively.

[0060] In this embodiment, two groups of sliding bars 9 are designed on both sides of the bottom of the metal base 1. The two groups of sliding bars 9 are not only symmetrical in position, but also have specific size specifications. The specifications are designed according to the ground shape of the metal base 1. The sliding bar 9 on one side is precisely sized to 6mm (width) × 119mm (length) × 5mm (height), ensuring stability and durability during installation and sliding. The sliding bar 9 on the other side is slightly longer, and its size is designed to be 6mm (width) × 126mm (length) × 5mm (height). Such a design may be to adapt to specific usage scenarios or needs, such as increasing the sliding stroke or providing additional support area. Both groups of sliding bars 9 provide important support for the overall structure and function realization of the metal base 1 with their precise size and reasonable layout.

[0061] It can be seen that by arranging the sliding bar 9 at the bottom of the metal base 1, the contact area between the base and other parts or surfaces is effectively increased, thereby improving the stability of the overall structure. This design is particularly suitable for application scenarios that need to withstand greater pressure or vibration, such as precision machinery, automation equipment and other fields. The design of the sliding bar 9 enables the metal base 1 to slide easily on a preset track or plane, which is convenient for users to fine-tune and position the position according to actual needs. This feature is particularly practical in situations where frequent adjustments to the position or angle are required, such as laboratory equipment, photographic equipment stands, etc. The sliding bar 9 is usually made of wear-resistant and corrosion-resistant materials, which can effectively resist wear and corrosion in daily use. This design extends the service life of the metal base 1 and its supported components, and reduces maintenance and replacement costs.

[0062] In some embodiments of the present application, the card slot type sample plate tray comprises four standard sample placement slots 3 and four to-be-tested sample placement slots 6, and the card slot type sample plate tray is used to place four standard samples and four square to-be-tested samples.

[0063] In this embodiment, the card slot type sample plate tray is divided into two main areas: a standard sample placement area and a test sample placement area. Each area is provided with four card slots to ensure that the samples are placed firmly. In the standard sample placement area, four standard sample placement slots 3 are evenly distributed according to a predetermined spacing. These standard samples are used as references or benchmarks for subsequent comparative analysis to ensure the accuracy and reliability of the test results. The test sample placement area is provided with four square test sample placement slots 6. These square test samples are the main objects of experiments or tests. By placing them in the card slots, various test operations such as sampling, analysis, comparison, etc. can be conveniently performed.

[0064] The entire card slot sample plate tray is made of high-quality materials, with a smooth surface, easy to clean and maintain. At the same time, its compact and reasonable structure not only saves space but also improves work efficiency. In addition, the tray also has good corrosion resistance and wear resistance, can adapt to various complex working environments, and ensure the safety of samples and the smooth progress of tests.

[0065] In some embodiments of the present application, springs are arranged on both sides of the standard sample placement slot 3, and the springs are used to fix the standard sample or the circular sample to be tested; double-sided tape is arranged in the sample placement slot 6, and the double-sided tape is used to stick and fix the square sample to be tested.

[0066] In this embodiment, spring devices are designed on both sides of the standard sample placement slot 3, and their main function is to ensure that both standard samples and circular samples to be tested can be firmly fixed in the placement slot to avoid displacement or falling off during the test or analysis process, thereby ensuring the accuracy and reliability of the test results. For the square samples to be tested, double-sided adhesive is used to fix them. High-quality double-sided adhesive is pre-pasted on the bottom wall of the sample placement slot 6 to be tested, which has strong and long-lasting viscosity and can easily firmly stick the square sample to be tested in the slot. This design not only simplifies the sample fixing steps and improves work efficiency, but also ensures the stability of the square sample during the test process, further improving the accuracy of the test.

[0067] It is understandable that by setting springs on both sides of the standard sample placement slot 3, standard samples or circular test samples of different sizes and shapes can be flexibly fixed without changing fixtures or adjusting equipment, thereby improving test efficiency and convenience. Double-sided tape is set in the test sample placement slot 6 to firmly stick and fix the square test sample, thereby avoiding displacement or falling off of the sample during the test and ensuring the accuracy and reliability of the test results. This technical solution achieves stable fixation of samples of different shapes through simple mechanical structure and material selection, without the need for complicated operating steps or additional fixing tools, thereby reducing the difficulty and cost of operation.

[0068] It can be seen that the circular standard sample placement groove 3 passes through the metal base 1 and is fixed by a spring; the square sample limit groove 4 passes through the metal base 1 and is fixed by the sample placement groove 6 of the push-pull sample plate 5 and a little double-sided tape. The fixing method of the standard sample and the sample to be tested makes the sample to be tested and the standard sample located in the same plane, thereby improving the accuracy of the experimental data.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
