[0025] In related technologies, heavy metal detection workstations are used to detect heavy metals in dairy products. The entire operation and control process of a heavy metal detection workstation typically requires manual operation by testing personnel, resulting in low testing efficiency.
[0026] In order to address the shortcomings of related technologies, Figure 1 This is a flowchart illustrating the operation control method for the heavy metal detection workstation provided by the present invention, as shown below. Figure 1 As shown, the method includes steps 110, 120, 130, 140 and 150.
[0027] Step 110: Control the weighing equipment to weigh a preset weight of dairy product sample.
[0028] Specifically, the execution entity of the heavy metal detection workstation operation control method provided in this embodiment of the invention is a heavy metal detection workstation operation control device. This device can be implemented in software, such as a heavy metal detection workstation operation control program or interface software; it can also be implemented in hardware, such as a processor, computer, or server that executes the heavy metal detection workstation operation control method.
[0029] 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 for testing, analysis, evaluation, or presentation. Heavy metal testing of dairy products refers to the detection of potentially harmful heavy metal elements in dairy products.
[0030] A heavy metal testing workstation is a facility for testing dairy products for heavy metals. It can be equipped with weighing equipment, transfer equipment, digestion equipment, and an inductively coupled plasma-mass spectrometer (ICP-MS). The various devices within the heavy metal testing workstation can be interconnected for automated control.
[0031] The weighing device can be an electronic balance. The weighing device can be controlled to weigh a preset weight of dairy product sample. For example, a container can be placed on the electronic balance, and a transfer device can be controlled to draw the dairy product sample from the sample bottle and gradually drip it into the container. The dripping stops when the reading on the electronic balance (excluding the container weight) equals the preset weight.
[0032] Step 120: Control the transfer device to transfer the dairy product sample from the weighing device to the digestion device.
[0033] Specifically, transfer devices, also known as pipetting equipment, are laboratory tools used for the precise transfer of liquids and are widely used in experimental operations in fields such as chemistry, life sciences, and medicine. They are typically used to transfer a specific amount of liquid from one container to another, or for operations such as dispensing, mixing, and quantifying liquids. Transfer devices can consist of multiple pipette tips and a robotic arm, enabling automated liquid dispensing and transfer.
[0034] After weighing the dairy product sample, the transfer device can be controlled to transfer the dairy product sample from the weighing device to the digestion device. Specifically, the dairy product sample is transferred from the initial container to the reagent tube or container that needs to be sent into the digestion device.
[0035] Step 130: Control the digestion equipment to digest the dairy product sample.
[0036] Specifically, digestion equipment is used in laboratories to chemically digest samples. Digestion refers to the reaction of a sample (usually a solid or liquid) with a strong acid or other chemical reagents under certain conditions, causing the organic or inorganic substances within the sample to decompose or dissolve, facilitating subsequent analysis or extraction. Digestion equipment is widely used in environmental monitoring, food safety, materials analysis, and other fields, especially for the quantitative analysis of elements such as metals in samples. Digestion equipment can include microwave digesters and electrothermal digesters, among others.
[0037] The digestion equipment can be controlled to digest dairy samples, yielding a digestion solution. The digestion solution is the solution obtained by adding a digesting agent (such as nitric acid, hydrofluoric acid, hydrochloric acid, etc.) or by using microwave heating to digest the dairy sample. This solution converts the organic matter and minerals in the sample into soluble forms.
[0038] Step 140: Control the transfer device to transfer the digested dairy product sample to the plasma mass spectrometer.
[0039] Specifically, after digestion is complete, the transfer device can be controlled to transfer the digested dairy product sample to the plasma mass spectrometer.
[0040] A plasma mass spectrometer 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 plasma mass spectrometer. The detection chamber is used for heavy metal detection in 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.
[0041] Step 150: Control the plasma mass spectrometer to detect the digested dairy product sample and generate the heavy metal detection results of the dairy product sample.
[0042] Specifically, a plasma mass spectrometer can be used to analyze digested dairy samples to determine the heavy metal detection results. The heavy metal detection results can indicate whether the dairy sample contains heavy metals, and if so, the types and amounts of those heavy metals.
[0043] In this embodiment of the invention, dairy product samples can be divided into multiple batches. Each batch is tested for heavy metals according to the method described above, which constitutes a sample sequence, and the samples are tested according to the sequence number. Multiple heavy metal elements can be detected simultaneously within each batch.
[0044] The heavy metal detection workstation operation control method provided in this invention controls a weighing device to weigh a preset weight of dairy product sample; controls a transfer device to transfer the dairy product sample from the weighing device to a digestion device; controls the digestion device to digest the dairy product sample; controls the transfer device to transfer the digested dairy product sample to a plasma mass spectrometer; and controls the plasma mass spectrometer to detect the digested dairy product sample, generating heavy metal detection results for the dairy product sample. This method automates the entire process of dairy product sample weighing, transfer, digestion, and detection without human intervention, avoiding the uncertainty risks associated with manual operation. It enables continuous sample injection and continuous detection, improving the detection efficiency and accuracy of the heavy metal detection workstation.
[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, before controlling the weighing device to weigh a preset weight of dairy product sample, the method further includes: Control the feeding equipment to grab the sample bottle containing dairy product samples and send it to the barcode scanning device; Control the barcode scanning device to identify the labels on the sample bottles and obtain the heavy metal testing requirements for the dairy product samples; Control the feeding equipment to grab the sample bottle and move it to the shaking device; Control the oscillation device to oscillate the sample vials; Control the feeding equipment to pick up the shaken sample bottles and transfer them to the capping equipment; Control the capping device to rotate the cap of the sample bottle to the open position.
[0047] Specifically, the heavy metal testing workstation can also be equipped with feeding equipment, barcode scanning equipment, vibration equipment, and capping equipment.
[0048] Feeding equipment is used to automatically grab sample bottles containing dairy product samples from production lines, storage areas, or sample sorting systems and send them to subsequent equipment for processing.
[0049] The barcode scanner is used to identify the labels on sample bottles and obtain the heavy metal testing requirements for the dairy product samples. The labels record basic information about the dairy product samples, including sample number, sample type, production date, production batch, and heavy metal testing requirements. This information can be recorded in the form of barcodes, QR codes, or electronic tags. Sample types can be categorized according to different dairy product types and testing purposes, typically based on the form of the dairy product, such as liquid, solid, and powdered dairy products. Furthermore, they can be differentiated based on user type. Heavy metal testing requirements refer to the specific needs and requirements for testing heavy metal content, including the types of heavy metals to be tested and the testing standards. Testing standards can include maximum residue limits for various heavy metals in dairy products.
[0050] A shaking device is a device that uses mechanical or electric means to vibrate or shake containers such as samples, solutions, and test tubes. The purpose of shaking is to promote processes such as dissolution, mixing, reaction, or extraction.
[0051] A capping device, also known as a capping machine, is a device used to tighten and loosen bottle caps on containers such as plastic and glass bottles after dispensing. The capping device can rotate the cap of the conveyor bottle, thus opening the sample bottle.
[0052] The feeding equipment, barcode scanning equipment, vibration equipment, and capping device can be interconnected with various devices in the heavy metal detection workstation for automated control.
[0053] The feeding device can be controlled to grab sample bottles containing dairy product samples and move them to the barcode scanning device. After barcode scanning and identification, the sample bottle is then grabbed to the vibration device, which vibrates the sample bottle. Finally, the vibrated sample bottle is grabbed to the capping device, which opens the cap.
[0054] The heavy metal detection workstation operation control method provided in this embodiment of the invention can also control the feeding equipment, barcode scanning equipment, oscillation equipment and capping device, enabling continuous sample feeding and continuous detection, thereby improving the detection efficiency of the heavy metal detection workstation.
[0055] In some embodiments, controlling the digestion equipment to digest dairy product samples includes: Based on the heavy metal detection requirements of the dairy product samples and the preset weight, the digestion configuration parameters and the amount of digestion reagent to be added are determined; the digestion configuration parameters include digestion temperature, digestion pressure and digestion time; Digestion reagent is added to the digestion tube containing the dairy product sample based on the amount of digestion reagent added; The digestion equipment is controlled based on the digestion configuration parameters to digest dairy product samples.
[0056] Specifically, dairy product samples have a complex composition, containing organic matter such as fat, protein, and lactose. Digestion may require strong acidic conditions to decompose these organic substances and release heavy metals. Therefore, it is necessary to select appropriate digestion reagents, temperatures, and times during the digestion process to ensure complete digestion without loss of heavy metals.
[0057] Based on the heavy metal testing requirements for the dairy product samples and the preset weight, determine the digestion configuration parameters and the amount of digestion reagent to be added. The main digestion parameters include digestion temperature, digestion pressure, and digestion time. A suitable digestion temperature can accelerate the digestion reaction and avoid excessive heavy metal loss. Digestion time depends on the complexity of the sample and the strength of the digestion reagent used. For some digestion methods, a digestion pressure setting is required. For example, microwave digesters are generally pressurized to maintain a liquid state at high temperatures, ensuring better sample digestion.
[0058] Depending on the amount of digesting reagent to be added, add the digesting reagent to the digestion tube containing the dairy product sample. Digesting reagents may include nitric acid, hydrofluoric acid, and hydrogen peroxide, etc.
[0059] The digestion configuration parameters can be used to control the digestion of dairy product samples, ensuring complete digestion of the dairy product samples.
[0060] The heavy metal detection workstation operation control method provided in this embodiment of the invention can automate the digestion process and improve the detection efficiency of the heavy metal detection workstation.
[0061] In some embodiments, controlling the transfer device to transfer the digested dairy product sample to a plasma mass spectrometer includes: The control transfer device transfers the digestion solution into the first reagent tube; The sample introduction mechanism of the plasma mass spectrometer is controlled to send the first and second reagent tubes into the detection chamber of the plasma mass spectrometer; The digestion solution is the solution obtained after digesting the dairy product sample; the second reagent tube is used to hold the standard solution for heavy metal comparison testing.
[0062] Specifically, 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 concentration) can be obtained. This response curve is used for quantitative calculations in subsequent sample analysis.
[0063] 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.
[0064] The transfer device can be controlled to transfer the digestion solution to the first reagent tube. Then, the sample introduction mechanism of the plasma mass spectrometer is controlled to send the first and second reagent tubes into the detection chamber of the plasma mass spectrometer for detection.
[0065] The heavy metal detection workstation operation control method provided in this embodiment of the invention realizes automated control of the sample introduction process of the plasma mass spectrometer, thereby improving the detection efficiency of the heavy metal detection workstation.
[0066] In some embodiments, before the sample introduction mechanism of the plasma mass spectrometer delivers the first reagent tube and the second reagent tube into the detection chamber of the plasma mass spectrometer, the method further includes: 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 results of the standard solution and the digestion solution are both qualified, the sample introduction mechanism of the plasma mass spectrometer is controlled to send the first and second reagent tubes into the detection chamber of the plasma mass spectrometer.
[0067] 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.
[0068] If the test result of the standard solution is unqualified, a first alarm message will be generated, prompting the user through voice and light, indicating that the standard solution needs to be manually checked and processed. If the test result of the digestion solution is unqualified, a second alarm message will be generated, prompting the user through voice and light, indicating that the digestion solution needs to be manually checked and processed.
[0069] If the test results of the standard solution and the digestion solution are both qualified, the sample introduction mechanism of the plasma mass spectrometer will send the first and second reagent tubes into the detection chamber of the plasma mass spectrometer for subsequent detection.
[0070] The heavy metal detection workstation operation control method provided in this embodiment of the invention performs detection before sending the digestion solution and standard solution corresponding to the dairy product sample into the plasma mass spectrometer, thereby improving the efficiency and accuracy of heavy metal detection in dairy products.
[0071] In some embodiments, a plasma mass spectrometer is controlled to detect the digested dairy product sample, generating heavy metal detection results for the dairy product sample, 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. 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.
[0072] Specifically, ignition and tuning are crucial steps in the operation of a plasma mass spectrometer. 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 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.
[0073] Tuning refers to adjusting various parameters of a plasma mass spectrometer to ensure the instrument operates efficiently and accurately, yielding reliable analytical data. The purpose of tuning is to optimize instrument performance and ensure analytical results possess high sensitivity, low background noise, good resolution, and accuracy.
[0074] The ignition and tuning parameters of the plasma mass spectrometer can be determined based on the heavy metal detection requirements.
[0075] 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.
[0076] If the plasma mass spectrometer is powered on, you only need to send the tuning configuration parameters to the 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.
[0077] The heavy metal detection workstation operation control method provided in this embodiment of the invention determines the ignition configuration parameters and tuning configuration parameters of the plasma mass spectrometer based on the heavy metal detection requirements, and controls the plasma mass spectrometer to ignite and tune in sequence, thereby improving the efficiency of heavy metal detection in dairy products.
[0078] In some embodiments, after controlling a plasma mass spectrometer to detect the digested dairy product sample and generating heavy metal detection results for the dairy product sample, the method further includes: 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 is written into the text position of the report field in the preset detection report template to generate a heavy metal detection report for dairy product samples.
[0079] 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.
[0080] 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.
[0081] The heavy metal detection workstation operation control method provided in this embodiment of the invention can automatically generate heavy metal detection reports without human intervention throughout the entire process, thereby improving the automation level of the heavy metal detection workstation.
[0082] Based on the above embodiments, this invention provides a heavy metal detection workstation operation process, which mainly includes digestion and detection steps.
[0083] Figure 2 This is a schematic flowchart of the dairy product sample digestion control method provided by the present invention, as shown below. Figure 2 As shown, it includes: Step 210: The sample enters the station from the sample sorting system. The loading robot (loading equipment) grabs the sample and completes the scanning (processed by the scanning equipment), vibration (processed by the vibration equipment), and capping (processed by the capping equipment).
[0084] Step 220: The sample is placed at the pick-up station, and the transfer robot picks up the sample and moves it to the pipetting station. The transfer robot places the digestion tube on the balance (weighing device), and the Z-axis robot (transfer device) completes the sample transfer and weighing.
[0085] Step 230: After weighing, the digestion robot grabs the tray and places it into the digester (digestion equipment), opens the channel, and completes the automatic digestion process.

Figure 3 As shown, it includes: Step 310: After the sample digestion is completed, transfer it to the post-processing station to complete the sample transfer.
[0087] Step 320: After the sample liquid to be tested is removed, the injector (injection mechanism) is automatically pushed to the injection station.
[0088] Step 330: The plasma mass spectrometer automatically completes the equipment hardware tuning and sample sequence establishment.
[0089] Step 340: After the sample testing is completed, the report will be automatically exported and submitted to the Laboratory Information Management System (LIMS) to complete the automatic testing process for rectification.
[0090] The heavy metal detection workstation operation control method provided by this invention has the following beneficial effects: (1) It can accurately weigh the sample to be tested, ensuring that the weighing accuracy is within the preset range, and can realize the continuous weighing of multiple samples, thus improving work efficiency.
[0091] (2) By monitoring parameters such as temperature and pressure during the digestion process in real time, the parameters are automatically adjusted according to the preset digestion program, ensuring the safety and effectiveness of digestion and making the sample completely digested.
[0092] (3) The operation of automatically removing the solution is completed with the help of a precision pipetting device. This device has the characteristics of anti-contamination, high precision and repeatability, ensuring that the sample is not contaminated and the pipetting volume is accurate during the pipetting process.
[0093] (4) Automatic control of the plasma mass spectrometer can automate the equipment startup, parameter setting, detection operation and data acquisition, ensuring accurate and efficient detection process.
[0094] The entire testing process, through the coordinated work of various automated links, greatly improves the accuracy, repeatability, and efficiency of the tests, reduces human error, and provides a reliable and efficient solution for the detection of heavy metals and other components in samples.
