Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0023] It should be noted that the terms "first," "second," etc., used in this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0024] In related technologies, heavy metals in dairy products are detected by inductively coupled plasma-mass spectrometry (ICP-MS), which usually requires a lot of manual intervention, such as sample preparation, instrument parameter setting, data acquisition and processing.

[0025] In order to address the shortcomings of related technologies, Figure 1 This is a schematic flowchart of the heavy metal detection method for dairy products provided by the present invention, as shown below. Figure 1 As shown, the method includes steps 110, 120, 130 and 140.

[0026] Step 110: Obtain the heavy metal testing requirements for dairy product samples.

[0027] Specifically, the execution entity of the dairy product heavy metal detection method provided in this embodiment of the invention is a dairy product heavy metal detection device. This device can be implemented in software, such as a dairy product heavy metal detection program or interface software; or it can be implemented in hardware, such as a processor, computer, or server that executes the dairy product heavy metal detection method.

[0028] Dairy products refer to various food products made from milk, goat milk, camel milk, and other dairy raw materials through processing. Dairy products are typically rich in protein, fat, vitamins, and minerals, especially calcium and phosphorus, making them an important source of nutrition for the human body. A dairy product sample refers to a sample obtained after taking samples of dairy products, used for testing, analysis, evaluation, or presentation of the dairy products.

[0029] Heavy metal testing in dairy products refers to the detection of potentially harmful heavy metals in dairy products. Heavy metal testing requirements information refers to the specific needs and requirements for testing heavy metal content, which may include the types of heavy metals to be tested and the testing standards. Testing standards may include maximum residue limits for various heavy metals in dairy products.

[0030] Step 120: Determine the configuration parameters of the plasma mass spectrometer based on the heavy metal detection requirements, and send the configuration parameters to the plasma mass spectrometer so that the plasma mass spectrometer can start up and run based on the configuration parameters.

[0031] Specifically, the measurement principle of plasma mass spectrometry is to vaporize and ionize the sample through a plasma source, and then use mass spectrometry to analyze these ions to determine the types and contents of elements.

[0032] When detecting heavy metals in dairy product samples, appropriate technical parameters of the plasma mass spectrometer should be selected and configured based on the heavy metal detection requirements to ensure the accuracy and reliability of the test results. Configuration parameters may include the types of heavy metals to be detected, detection sensitivity, analysis speed, plasma source power, and mass spectrometry analysis mode.

[0033] Configuration parameters can be sent to the plasma mass spectrometer, allowing the spectrometer to make relevant settings based on these parameters and then power on and run.

[0034] Step 130: Send the digestion solution and standard solution corresponding to the dairy product sample into the plasma mass spectrometer so that the plasma mass spectrometer can detect the digestion solution and standard solution to determine the heavy metal detection results of the dairy product sample.

[0035] Specifically, an inductively coupled plasma mass spectrometer (ICP-MS) includes at least a detection chamber and a sample introduction mechanism. The sample introduction mechanism is used to deliver the sample into the detection chamber of the ICP-MS. The detection chamber is used for heavy metal detection of the sample. The sample introduction mechanism can accurately control the injection volume and injection speed, enabling automatic sample introduction and initiation of the detection process.

[0036] Dairy products typically contain complex components such as fats, proteins, carbohydrates, and minerals, and inductively coupled plasma mass spectrometry (ICP-MS) usually requires the analysis of elemental composition in samples. Therefore, to ensure that all elements (such as calcium, magnesium, and sodium) can enter the analyzer's system in a soluble form, the complex organic components in dairy products (such as fats and proteins) must be completely digested into inorganic salts or solutions. This can be achieved through acid digestion.

[0037] A digestion solution is a solution obtained by digesting dairy product samples by adding a digesting agent (such as nitric acid, hydrofluoric acid, hydrochloric acid, etc.) or by using microwave heating. This solution converts the organic matter and minerals in the sample into soluble forms.

[0038] Standard solutions are used to calibrate the plasma mass spectrometer. By measuring the response of elements of known concentration in the standard solution, the instrument's response curve (typically the relationship between the mass spectrometer's signal intensity and the element's concentration) can be obtained. This response curve is used for quantitative calculations in subsequent sample analysis.

[0039] The digestion solution and standard solution corresponding to the dairy product sample were sent to an inductively coupled plasma mass spectrometer (ICP-MS). The ICP-MS can analyze the standard solution and digestion solution to determine the heavy metal detection results of the dairy product sample, such as the heavy metals contained and their content.

[0040] The working process of a plasma mass spectrometer can be as follows: First, calibration is performed using a standard solution, the elements in the standard solution are measured, and a response curve is plotted; second, the digestion solution is analyzed, and the mass spectrometric response of each element is measured; finally, based on the response curve and using the data from the standard solution, the concentration or content of the target element in the dairy product sample is calculated.

[0041] Step 140: Based on the heavy metal detection results of the dairy product samples, generate a heavy metal detection report for the dairy product samples.

[0042] Specifically, based on the heavy metal test results of dairy product samples, a heavy metal test report for dairy product samples can be automatically generated according to the relevant report template, saving time for users (testing personnel); the heavy metal test report can also be displayed on the screen.

[0043] In this embodiment of the invention, dairy product samples can be divided into multiple batches, and each batch is tested for heavy metals according to the method described above, which constitutes a sample sequence and is tested according to the sequence number. Multiple heavy metal elements can be detected simultaneously within each batch.

[0044] The heavy metal detection method for dairy products provided in this invention involves: acquiring heavy metal detection requirement information corresponding to dairy product samples; determining the configuration parameters of an inductively coupled plasma mass spectrometer (ICP-MS) based on the heavy metal detection requirement information and sending the configuration parameters to the ICP-MS so that the ICP-MS can start operating based on the configuration parameters; sending the digestion solution and standard solution corresponding to the dairy product sample into the ICP-MS so that the ICP-MS can detect the digestion solution and standard solution to determine the heavy metal detection results of the dairy product sample; and generating a heavy metal detection report of the dairy product sample based on the heavy metal detection results. Since the configuration parameters are generated by using the heavy metal detection requirement information corresponding to the dairy product sample to configure the ICP-MS, the ICP-MS can automatically analyze the digestion solution and standard solution corresponding to the dairy product sample to generate heavy metal detection results. The entire process requires no manual intervention and can achieve continuous sample introduction and continuous detection, thus improving the efficiency and accuracy of heavy metal detection in dairy products.

[0045] It should be noted that each embodiment of the present invention can be freely combined, rearranged, or executed individually, and does not need to rely on or depend on a fixed execution order.

[0046] In some embodiments, obtaining heavy metal testing requirements for dairy product samples includes: The control and identification equipment identifies the sample labels of dairy product samples to obtain the sample type of the dairy product samples; Based on the sample type of dairy product samples, a search is conducted in the database to determine the corresponding heavy metal testing requirements for dairy product samples. The database stores multiple sample types of dairy products, as well as the heavy metal testing requirements for each sample type.

[0047] Specifically, sample labels for dairy products are used to record basic information about the samples, including sample number, sample type, production date, and production batch. This information can be recorded in the form of barcodes, QR codes, or electronic tags. Sample types can be classified according to different types of dairy products and testing purposes. They are typically classified according to the form of the dairy product, such as liquid dairy products, solid dairy products, and powdered dairy products. Furthermore, they can also be differentiated based on user type.

[0048] The identification device can be an image recognition device used to identify barcode or QR code type sample labels to obtain the sample type of dairy product samples; or it can be an electronic tag reader used to identify electronic tag type sample labels to obtain the sample type of dairy product samples.

[0049] Understandably, the requirements for heavy metal testing differ depending on the type of dairy product sample. For example, different regions have different standards for testing the heavy metal content of dairy products; when powdered dairy products are formula milk powder, the standards for testing heavy metal content are very strict.

[0050] The database can be used to store heavy metal testing requirements for different sample types and updated regularly. After obtaining the sample type of a dairy product, the database can be searched to determine the corresponding heavy metal testing requirements.

[0051] The heavy metal detection method for dairy products provided in this invention improves the efficiency and accuracy of heavy metal detection by storing heavy metal detection requirements for various sample types of dairy products, making it convenient for users to query and use the information.

[0052] In some embodiments, the configuration parameters of the plasma mass spectrometer are determined based on heavy metal detection requirements, and the configuration parameters are sent to the plasma mass spectrometer, including: The ignition and tuning configuration parameters of the plasma mass spectrometer are determined based on the requirements for heavy metal detection. With the plasma mass spectrometer powered off, the ignition configuration parameters and tuning configuration parameters are sent to the plasma mass spectrometer in sequence, so that the plasma mass spectrometer can be powered on and ignited based on the ignition configuration parameters, and the parameters can be adjusted based on the tuning configuration parameters.

[0053] Specifically, ignition and tuning are crucial steps in the operation of a plasma mass spectrometer.

[0054] Ignition refers to the process of starting the plasma. In a plasma mass spectrometer, the plasma is generated by a high-frequency electromagnetic induction coil. It requires gas flow and electromagnetic induction heating to reach a sufficient temperature and maintain a stable state. The ignition process typically involves gas flow, high-frequency electromagnetic field initiation, and temperature rise. The purpose of ignition is to ensure plasma stability and efficient ionization of the sample entering the mass spectrometry analysis section. Once the plasma is ignited and stabilized, the instrument can begin receiving and analyzing the sample.

[0055] Tuning refers to adjusting various parameters of a plasma mass spectrometer to ensure efficient and accurate operation and obtain reliable analytical data. The purpose of tuning is to optimize instrument performance and ensure analytical results with high sensitivity, low background noise, good resolution, and accuracy. The tuning process typically includes optimizing plasma stability and temperature, optimizing the ion lens system, and suppressing background noise.

[0056] Accordingly, the ignition and tuning configuration parameters of the plasma mass spectrometer can be determined based on the heavy metal detection requirements.

[0057] If the plasma mass spectrometer is powered off, the ignition and tuning configuration parameters can be sent to the spectrometer sequentially. This will control the spectrometer to ignite and tune in sequence. Ignition is performed according to the ignition configuration parameters, and parameter adjustments are made according to the tuning configuration parameters. After the ignition and tuning processes are completed, all parts of the plasma mass spectrometer will be in optimal condition, allowing for accurate analysis of dairy samples.

[0058] The heavy metal detection method for dairy products provided in this invention determines the ignition and tuning parameters of the plasma mass spectrometer based on the heavy metal detection requirements, and controls the plasma mass spectrometer to ignite and tune sequentially, thereby improving the efficiency and accuracy of heavy metal detection in dairy products.

[0059] In some embodiments, after determining the ignition configuration parameters and tuning configuration parameters of the plasma mass spectrometer based on heavy metal detection requirements, the method further includes: With the plasma mass spectrometer powered on, the tuning configuration parameters are sent to the plasma mass spectrometer so that the plasma mass spectrometer can adjust its parameters based on the tuning configuration parameters.

[0060] Specifically, if the plasma mass spectrometer is powered on, it is only necessary to send the tuning configuration parameters to the plasma mass spectrometer, which will then adjust the parameters accordingly. After the tuning process is complete, all parts of the plasma mass spectrometer will be in optimal condition, allowing for accurate analysis of dairy samples.

[0061] The method for detecting heavy metals in dairy products provided in this invention improves the efficiency and accuracy of heavy metal detection by controlling the plasma mass spectrometer to adjust its parameters according to the tuning configuration parameters when the plasma mass spectrometer is powered on.

[0062] In some embodiments, the digestion solution and standard solution corresponding to the dairy product sample are fed into an inductively coupled plasma mass spectrometer, including: The control and detection equipment is used to detect the standard solution and the digestion solution to obtain the detection results of the standard solution and the digestion solution. If the test result of the standard solution is unqualified, a first alarm message will be sent; the first alarm message is used to prompt manual inspection and handling of the standard solution. If the test results of the digestion solution are unqualified, a second alarm message will be sent; the second alarm message is used to prompt manual inspection and handling of the digestion solution.

[0063] Specifically, before sending the standard solution and digestion solution into the plasma mass spectrometer, the sample needs to be tested to ensure it meets the analytical requirements and yields accurate results. The quality of the sample directly affects the accuracy and reliability of the analytical results. Typically, the acidity, clarity, completeness of digestion of the digestion solution, concentration, and composition of the standard solution need to be tested. Correspondingly, the testing equipment may include pH meters and image recognition devices.

[0064] If the test result of the standard solution fails, a first alarm message can be generated. The first alarm message can be displayed to the user via voice, light, or other means, indicating that the standard solution needs to be manually checked and processed.

[0065] If the test results of the digestion solution are unqualified, a second alarm message can be generated. The second alarm message can prompt the user through voice, light, or other means, indicating that the digestion solution needs to be manually inspected and processed.

[0066] The method for detecting heavy metals in dairy products provided in this invention improves the efficiency and accuracy of heavy metal detection by performing the detection before sending the digestion solution and standard solution corresponding to the dairy product sample into the plasma mass spectrometer.

[0067] In some embodiments, a heavy metal detection report for dairy product samples is generated based on the heavy metal detection results, including: Obtain a preset test report template; the preset test report template includes multiple report fields; Match the detection fields in the heavy metal test results with the report fields in the preset test report template; If the detection field and the report field are consistent, the data corresponding to the detection field will be written to the text position of the report field in the preset detection report template.

[0068] Specifically, a preset test report template can be set. The preset test report template includes multiple report fields, each corresponding to a specific heavy metal test item. The heavy metal test results can also include multiple test fields, each also corresponding to a specific heavy metal test item.

[0069] A field matching method can be used to match the detection fields in the heavy metal test results with the report fields in the preset test report template. If they match, the data corresponding to the detection fields in the heavy metal test results is written into the text position of the report field in the preset test report template. This method allows for the automated import of data from heavy metal test results into the preset test report template, thereby generating a heavy metal test report.

[0070] The heavy metal detection method for dairy products provided in this invention can automatically generate heavy metal detection reports without human intervention throughout the entire process, thus improving the efficiency of heavy metal detection in dairy products.

[0071] In some embodiments, after generating a heavy metal detection report for dairy product samples based on the heavy metal detection results, the process includes: Send a shutdown command to the plasma mass spectrometer; the shutdown command is used to control the plasma mass spectrometer to perform automatic cleaning and shutdown.

[0072] Specifically, after generating the heavy metal test report and confirming that all dairy product samples have been tested, a shutdown command can be sent to the plasma mass spectrometer. This command controls the plasma mass spectrometer to automatically clean and shut down.

[0073] Some plasma mass spectrometers offer automated cleaning programs to clean the sample introduction system, including the inlet, nebulizer, and spray chamber. This is typically done by recycling cleaning solutions (such as deionized water, dilute acid solutions, or specialized cleaning solutions) to remove residual sample and solution, reducing sample contamination.

[0074] Flameout refers to shutting down the plasma processing, typically occurring after analysis or when the instrument has been idle for an extended period. Proper flameout procedures can protect the instrument and prevent damage.

[0075] The method for detecting heavy metals in dairy products provided in this invention automatically cleans and shuts down the plasma mass spectrometer (plasma shut-off) after the heavy metal detection is completed, which can ensure instrument performance, improve analytical accuracy, extend service life, and reduce equipment failure.

[0076] Based on the above embodiments, Figure 2 This is a flowchart illustrating the detection and control method for an inductively coupled plasma mass spectrometer (ICP-MS) provided by this invention. An ICP-MS typically includes a sample introduction mechanism, a detection chamber, and a control system. The control system further includes hardware (PLC) and software programs. For example... Figure 2 As shown, the method includes: Step 210: The robotic arm will transfer the sample from the digestion tube to the centrifuge tube after the sample comes out of the digestion instrument. After the transfer of this batch is completed, the PLC will set the "DB600.0.3" signal to true.

[0077] Step 220: After the software program reads this signal, it knows that the pipetting is complete. It will send "DB400.152.0" to true to turn on the exhaust fan, and set "DB600.8.0" and "DB600.8.1" to true to move the two injection mechanisms to the ICP-MS.

[0078] Step 230: After the sample injection mechanism has moved, the software program will send a status query request to check the current ICP-MS status. If the ICP-MS is in the off state, the ignition and tuning commands will be sent in sequence to notify the ICP-MS to turn on.

[0079] Step 240: After the ICP-MS is started, the software program will read the quantity of samples in this batch and the type of detection. It will then encapsulate this information into corresponding parameters and send an HTTP request to the ICP-MS to initiate the detection.

[0080] Step 250: Monitor the ICP-MS test results. If the results are satisfactory, save the file and upload it to the Laboratory Information Management System (LIMS). If the results are unsatisfactory, an alarm will be triggered to notify manual processing.

[0081] Step 260: After the test is completed, the software program notifies the ICP-MS to perform cleaning and shut down the engine.

[0082] The method provided in this invention uses an automatic detection control method to improve detection efficiency, reduce manual operation, achieve continuous detection, optimize the detection process, and improve detection accuracy and reliability without the need for manual intervention.

[0083] The apparatus provided in the embodiments of the present invention will be described below. The apparatus described below can be referred to in correspondence with the method described above.

[0084] Figure 3 This is a schematic diagram of the structure of the heavy metal detection device for dairy products provided by the present invention, as shown below. Figure 3 As shown, the device includes: The acquisition unit 310 is used to acquire the heavy metal detection requirement information corresponding to the dairy product sample; Configuration unit 320 is used to determine the configuration parameters of the plasma mass spectrometer based on the heavy metal detection requirement information, and send the configuration parameters to the plasma mass spectrometer so that the plasma mass spectrometer can start up and run based on the configuration parameters; The detection unit 330 is used to send the digestion solution and standard solution corresponding to the dairy product sample into the plasma mass spectrometer so that the plasma mass spectrometer can detect the digestion solution and standard solution to determine the heavy metal detection results of the dairy product sample. Reporting unit 340 is used to generate a heavy metal test report for dairy product samples based on the heavy metal test results.

[0085] The heavy metal detection device for dairy products provided in this invention acquires heavy metal detection requirement information corresponding to dairy product samples; determines the configuration parameters of an inductively coupled plasma mass spectrometer (ICP-MS) based on the heavy metal detection requirement information, and sends the configuration parameters to the ICP-MS so that the ICP-MS can start operating based on the configuration parameters; sends the digestion solution and standard solution corresponding to the dairy product sample into the ICP-MS so that the ICP-MS can detect the digestion solution and standard solution to determine the heavy metal detection results of the dairy product sample; and generates a heavy metal detection report for the dairy product sample based on the heavy metal detection results. Because the configuration parameters are generated by using the heavy metal detection requirement information corresponding to the dairy product sample to configure the ICP-MS, the ICP-MS can automatically analyze the digestion solution and standard solution corresponding to the dairy product sample and generate heavy metal detection results. The entire process requires no manual intervention and can achieve continuous sample introduction and continuous detection, thus improving the efficiency and accuracy of heavy metal detection in dairy products.

[0086] Figure 4 This is a schematic diagram of the structure of the electronic device provided by the present invention, such as... Figure 4 As shown, the electronic device may include: a processor 410, a communications interface 420, a memory 430, and a communications bus 440, wherein the processor 410, the communications interface 420, and the memory 430 communicate with each other via the communications bus 440. The processor 410 can call logical commands stored in the memory 430 to execute the methods described in the above embodiments, for example: Obtain the heavy metal detection requirements for dairy product samples; determine the configuration parameters of the plasma mass spectrometer (PMS) based on the heavy metal detection requirements, and send the configuration parameters to the PMS to enable it to start operating; send the digestion solution and standard solution corresponding to the dairy product samples into the PMS to enable it to detect the digestion solution and standard solution and determine the heavy metal detection results of the dairy product samples; generate a heavy metal detection report for the dairy product samples based on the heavy metal detection results.
