[0043] With the rapid development of fields such as environmental monitoring, food safety, and biomedicine, sample pretreatment has become increasingly important in analytical chemistry. In the laboratory, both food and environmental solid samples have complex compositions, containing small and large molecules as well as various inorganic elements. Before determining the elements in solid samples, pretreatment is necessary to ensure the accuracy and reliability of the results. Sample pretreatment refers to the preparation of the sample and the extraction, purification, and concentration of the analyte, transforming it into a measurable form for qualitative and quantitative analysis.

[0044] Sample pretreatment is a time-consuming and error-prone step in instrumental analysis, directly impacting the final analytical results. Graphite digestion is a commonly used technique that utilizes the thermal conductivity of graphite at high temperatures to promote the decomposition of organic matter in samples, making it particularly suitable for the pretreatment of metal ions and elemental analysis. However, different types of samples require varying temperatures, times, and types and concentrations of acids for digestion. Traditional sample digestion methods are often inefficient, especially for complex samples, frequently suffering from long digestion times and incomplete reactions, ultimately affecting the accuracy of the analytical results.

[0045] To address the aforementioned problems, embodiments of this application provide a sample processing apparatus, method, and electronic device. The sample processing apparatus includes a digestion module, a motion-assisted liquid addition module, and a control module. The motion-assisted liquid addition module includes a driving component, a liquid addition component, a waste discharge component, and a liquid collection component. The driving component is used to drive the liquid addition component and the waste discharge component to move, thereby realizing the liquid addition operation and the waste discharge operation. The digestion module includes a graphite disk that carries a sample test tube, thereby enabling the sample test tube to be heated and digested through the graphite disk. The digestion processing of the sample to be digested is achieved through the cooperation of the motion-assisted liquid addition module and the digestion module. Specifically, in the sample processing, this embodiment first controls the drive component to move, thereby moving the liquid addition component to the liquid collection component. The liquid addition component then draws the digestion reagent from the liquid collection component, enabling precise liquid collection. Next, the drive component moves the liquid addition component to the sample tube on the graphite disk, and the liquid addition component adds the drawn digestion reagent into the sample tube, ensuring close contact between the digestion reagent and the sample. Then, the graphite disk heats and digests the sample and the digestion reagent in the sample tube, allowing a chemical reaction to occur at a specified temperature, decomposing the organic matter in the sample and yielding the digestion result. Finally, the drive component moves, moving the waste removal component to the sample tube on the graphite disk, and the waste removal component draws the digestion waste liquid from the sample tube, removing unwanted impurities and obtaining the target digested sample. This improves digestion efficiency and further enhances the accuracy of the analytical results. In this embodiment, the thermal conductivity of graphite material at high temperature is used to promote the decomposition of organic matter in the sample. By introducing graphite digestion technology, the sample can be effectively digested in a short time, which improves the digestion efficiency. Furthermore, the cooperation between the digestion module and the motion liquid addition module reduces the workload of the operator and improves the overall efficiency of sample processing.

[0046] As can be seen from the above, existing patents or methods, such as wet digestion (e.g., hot plate digestion), are simple to operate but time-consuming, require large amounts of acid, and are prone to contamination and element loss; dry ashing is suitable for organic samples, but high temperatures can easily lead to the loss of volatile elements (e.g., Hg, Pb), and the sample volume is limited; microwave digestion rapidly decomposes samples under closed high pressure, requiring less acid and achieving high element recovery rates, but the equipment cost is high and the sample volume is limited. This application utilizes the thermal conductivity of graphite materials at high temperatures to promote the decomposition of organic matter in the sample. By introducing graphite digestion technology, effective sample digestion can be completed in a short time. Compared to existing patents or methods, the embodiments of this application improve digestion efficiency, and through the cooperation of the digestion module and the motion-assisted liquid addition module, the workload of operators is reduced, and the overall efficiency of sample processing is improved.

[0048] In some embodiments, the sample processing apparatus includes, but is not limited to, a digestion module 100, a motion-assisted liquid dispensing module 200, and a control module 900.

[0049] The digestion module 100 includes a graphite disk 110, which is used to hold a sample tube for heating and digesting the sample in the sample tube. The sample tube contains a sample to be digested, so that the sample to be digested in the sample tube can be directly digested on the graphite disk 110.

[0050] It should be noted that one or more graphite disks 110 can be provided in the embodiments of this application, and each graphite disk 110 is provided with multiple digestion holes, such as ten digestion holes, fifteen digestion holes, twelve digestion holes, etc. The digestion holes are used to fix the sample test tubes. The size of the digestion holes can be set according to the size of the sample test tubes. This application embodiment does not impose specific limitations.

[0051] Reference Figure 2 , Figure 2 This is a schematic diagram of the frame of a sample processing device provided in another embodiment of this application.

[0052] In some embodiments, the sample processing device further includes a workbench 400 and a protective housing. The digestion module 100, the motion liquid addition module 200, and the control module 900 are disposed on the workbench 400. The protective housing covers the periphery of the workbench 400 to form a working space, thereby protecting the sample processing device, preventing the sample processing device from being interfered with by external factors during the digestion process, and further improving the accuracy of the analysis results.

[0053] In some embodiments, the motion liquid addition module 200 includes a driving component 210, a liquid addition component 220, a waste discharge component 230, and a liquid collection component 240. The liquid collection component 240 stores a digestion reagent, which is used to react with the sample to be digested in the sample tube. The driving component 210 is provided with a support frame, and the waste discharge component 230 and the liquid addition component 220 are respectively provided on the support frame, thereby saving space and realizing reasonable space planning of the motion liquid addition module 200. The driving component 210 is used to drive the liquid addition component 220 and the waste discharge component 230 to move, thereby enabling flexible movement of the liquid addition component 220 and the waste discharge component 230, which facilitates the subsequent liquid addition process and waste discharge process.

[0054] In some embodiments, the drive assembly 210 includes a three-dimensional robotic arm and a drive motor. The drive motor is connected to the three-dimensional robotic arm to drive the three-dimensional robotic arm to move. The three-dimensional robotic arm adopts a three-Z-axis design. The liquid filling assembly 220 and the waste discharge assembly 230 are respectively disposed at the two Z-axis ends of the three-dimensional robotic arm to fix the liquid filling assembly 220 and the waste discharge assembly 230 and prevent movement during the liquid filling or discharge process.

[0055] It should be noted that the liquid collection component 240 in the embodiments of this application can be a liquid collection tank, a liquid collection bottle, etc. The number of liquid collection components 240 can be determined according to the type of digestion reagent. For example, if there are four types of digestion reagents, four liquid collection components 240 can be set; if there are six types of digestion reagents, six liquid collection components 240 can be set, etc. The embodiments of this application do not impose specific limitations.

[0056] The control module 900 is communicatively connected to both the digestion module 100 and the liquid addition module 200. The control module 900 controls the movement of the drive component 210 to move the liquid addition component 220 to the liquid collection component 240, and controls the liquid addition component 220 to draw the digestion reagent from the liquid collection component 240. This allows the liquid addition component 220 to be moved to a designated position for precise liquid collection. The drive component 210 then moves the liquid addition component 220 to the sample tube on the graphite disk 110, and controls the liquid addition component 220 to add the drawn digestion reagent into the sample tube, thus adding the digestion reagent to the sample tube. The digestion reagent is brought into close contact with the sample to be digested. Then, the sample and digestion reagent in the sample tube are heated and digested using a graphite disk 110. This allows a chemical reaction to occur between the digestion reagent and the sample at a specified temperature, decomposing the organic matter in the sample and yielding the digestion result. The drive component 210 is then moved to move the waste discharge component 230 to the sample tube on the graphite disk 110, and the waste discharge component 230 removes the digestion waste liquid from the sample tube, removing unwanted impurities and obtaining the target digested sample. This improves digestion efficiency and further enhances the accuracy of the analytical results. In this embodiment, the thermal conductivity of graphite at high temperatures is used to promote the decomposition of organic matter in the sample. By introducing graphite digestion technology, effective sample digestion can be completed in a short time, improving digestion efficiency. Furthermore, the cooperation between the digestion module 100 and the motion-assisted liquid addition module 200 reduces the workload of operators and improves the overall efficiency of sample processing.

[0057] Understandably, traditional sample digestion methods are often inefficient, especially for complex samples, frequently suffering from long processing times and incomplete reactions. This application's embodiment, by introducing graphite digestion technology, enables efficient sample digestion in a short time, significantly improving work efficiency. Due to the use of graphite digestion technology, the sample processing device of this application maintains high digestion stability, ensuring consistent digestion results for each sample processed, exhibiting good repeatability and accuracy. Furthermore, this sample processing device can process multiple samples simultaneously, reducing operator workload and improving overall sample processing efficiency. This is particularly advantageous in applications requiring the processing of large numbers of samples.

[0058] In some embodiments, the digestion module 100 further includes a lifting assembly 120, which includes a lifting motor and a lifting bracket. The lifting bracket is connected to the graphite disk 110. The lifting motor is used to drive the lifting bracket to move along a first preset direction, so as to drive the graphite disk 110 to move along the first preset direction, so as to raise or lower the graphite disk 110 and realize the lifting of the graphite disk 110.

[0059] It should be noted that the number of lifting brackets in this application embodiment can be set according to the number of graphite disks 110. For example, when there are two graphite disks 110, the number of lifting brackets is set to two; when there are four graphite disks 110, the number of lifting brackets is four, and so on. This application embodiment does not impose specific limitations.

[0060] It is understood that the first preset direction in the embodiments of this application can be the Z-axis direction of the graphite disk 110.

Specifically, it is disposed at the Z-axis end of the three-dimensional robotic arm of the drive component 210. The gripping component 250 is used to grip the sample tube, which facilitates the movement of the sample tube and enables the oscillation of the sample tube.

As those skilled in the art will know, with the evolution of sample processing apparatus and the emergence of new application scenarios, the technical solutions provided by the embodiments of the present invention are also applicable to similar technical problems.

[0070] It will be understood by those skilled in the art that Figures 1 to 4 The sample processing apparatus shown does not constitute a limitation on the embodiments of the present invention and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0071] Reference Figure 3 , Figure 3 This is a flowchart illustrating a specific method of the sample processing method provided in the embodiments of this application. In some embodiments, the sample processing method applies, but is not limited to, [specific methods]. Figure 1 The sample processing device and method include, but are not limited to, steps S101 to S104.

[0072] In step S101, the drive component 210 is controlled to move to move the liquid addition component 220 to the liquid collection component 240, and the liquid addition component 220 is controlled to draw the digestion reagent from the liquid collection component 240.

[0073] In step S101 of some embodiments, the present application embodiment first controls the drive component 210 to move to drive the liquid addition component 220 to the liquid collection component 240, so as to move the liquid addition component 220 to the designated position, and controls the liquid addition component 220 to draw the digestion reagent in the liquid collection component 240. Specifically, the present application embodiment lowers the liquid addition component 220 by the drive component 210 so that the liquid addition needle and liquid addition channel of the liquid addition component 220 can be immersed in the digestion reagent in the liquid collection component 240. Then, the liquid addition component 220 is controlled to draw the digestion reagent in the liquid collection component 240, thereby realizing the absorption of the digestion reagent and filling the liquid addition channel with the digestion reagent, which facilitates the subsequent digestion treatment of the sample in the sample tube.

[0074] In step S102, the liquid addition component 220 is moved to the sample tube of the graphite disk 110 by the drive component 210, and the liquid addition component 220 is controlled to add the absorbed digestion reagent into the sample tube.

[0075] In step S102 of some embodiments, the liquid addition component 220 is moved to the sample tube of the graphite disk 110 by the driving component 210. Specifically, after the reagent pre-filling of the liquid addition component 220 is completed, the liquid addition component 220 is moved by the driving component 210 so that the liquid addition channel of the liquid addition component 220 is lowered to the sample tube, and the liquid addition component 220 is controlled to add the absorbed digestion reagent into the sample tube, thereby realizing the liquid addition treatment of the sample tube.

[0076] Step S103: The sample to be digested and the digestion reagent in the sample test tube are heated and digested through the graphite disk 110 to obtain the digestion result, which includes the digestion waste liquid.

[0077] In step S103 of some embodiments, the sample to be digested and the digestion reagent in the sample tube are heated and digested by the graphite disk 110. The digestion causes the sample to be digested and the digestion reagent to react chemically, removing unwanted impurities and obtaining the digestion result, thereby improving the accuracy of the analysis result.

[0078] In step S104, the drive component 210 is controlled to move so as to move the waste discharge component 230 to the sample tube of the graphite disk 110, and the waste discharge component 230 is controlled to absorb the digestion waste liquid in the sample tube to obtain the target digestion sample.

[0079] In step S104 of some embodiments, the drive component 210 is controlled to move to move the waste discharge component 230 to the sample tube of the graphite disk 110. Specifically, the drive component 210 controls the waste discharge channel and waste discharge needle in the waste discharge component 230 to be inserted into the sample tube, and controls the waste discharge component 230 to draw up the digestion waste liquid in the sample tube. The waste is discharged by the peristaltic pump in the waste discharge component 230, thereby discharging the waste liquid and obtaining the target digestion sample. This reduces the time of manual operation, avoids the influence of waste liquid residue on subsequent experimental steps, and ensures the accuracy and reliability of the experimental results.

In some embodiments, the method includes, but is not limited to, steps S201 to S203.

[0081] It should be noted that the motion-assisted liquid dispensing module 200 also includes a gripping component 250.

[0082] Step S201: Control the graphite disk 110 to heat and dissolve the sample to be digested and the digestion reagent in the sample tube for a first preset heating and dissolution time to obtain the first reagent.

[0083] In step S202, after the first preset heating and dissolving time, the liquid addition component 220 is controlled to add the absorbed digestion reagent back into the first reagent to obtain the second reagent.

[0084] In step S203, the graphite disk 110 is controlled to perform a reconstitution operation on the second reagent in the sample tube for a second preset heating and dissolution time to obtain the digestion result.

[0085] In steps S201 to S203 of some embodiments, during the process of heating and digesting the sample to be digested and the digesting reagent in the sample tube using the graphite disk 110, the embodiments of this application first control the graphite disk 110 to heat and dissolve the sample to be digested and the digesting reagent in the sample tube for a first preset heating and dissolution time, so as to achieve full dissolution of the sample to be digested and the digesting reagent. The thermal conductivity of graphite material at high temperature is used to promote the decomposition of organic matter in the sample to be digested, which can complete the effective digestion of the sample in a short time, obtaining the first reagent, and achieving the initial digestion of the sample to be digested. After the first preset heating and dissolution time... The control drive component 210 moves to drive the liquid addition component 220 to move again to the liquid collection component 240. The control liquid addition component 220 adds the absorbed digestion reagent back into the first reagent, that is, adds the digestion reagent to the sample reagent again to obtain the second reagent. Then, the control graphite disk 110 performs a re-dissolution operation on the second reagent in the sample tube for a second preset heating and dissolution time, so that the sample to be digested in the sample tube can be fully dissolved with the digestion reagent to obtain the digestion result. Through digestion, the sample to be digested in the sample tube undergoes a chemical reaction with the digestion reagent, removing unwanted impurities and improving the accuracy of the analysis results.

[0086] It should be noted that the first preset heating and dissolving time and the second preset heating and dissolving time in the embodiments of this application can be set by the user according to their needs, and the first preset heating and dissolving time and the second preset heating and dissolving time can be the same or different. The embodiments of this application do not impose specific limitations.
