[0022] To determine the components and their concentrations in a liquid sample, it is necessary to dilute it to a fixed volume, measure the volume, and then compare the results with a standard curve to obtain accurate data.

[0023] Existing liquid sample diluents can achieve batch transfer and dilution, but when configuring standard curves, they can often only be configured to aspirate the same amount of sample. If precise differential ratios are required, samples need to be aspirated from each test tube individually. This setup is not only inefficient, but also may lead to problems such as mixed contamination or incorrect aspiration measurements when aspirating samples from each test tube individually.

[0024] like Figure 1 As shown, Figure 1 This is a schematic diagram of the control method of the diluent of this application. The diluent 1 includes: a spray suction element 8, a liquid dispensing component 10 and a dilution component 11. The spray suction element 8 is used to draw or dispense liquid. In some embodiments, the spray suction element 8 is a liquid inlet needle. The liquid separation assembly 10 includes a liquid separation drive 2 and a liquid separation valve 18. The liquid separation valve 18 connects the liquid separation drive 2 and the suction nozzle 8. The liquid separation valve 18 is used to control the liquid separation drive 2 to draw in or release the experimental liquid. In some embodiments, the liquid separation drive 2 is a sampling pump. The liquid separation drive 2 draws the experimental liquid into the pump body through the suction nozzle 8 via the movement of the pump body, and releases it when needed. Meanwhile, the liquid separation valve 18 can be, but is not limited to, a solenoid valve. The liquid separation valve 18 is used to control the specific volume of experimental liquid entering the liquid separation drive 2 and the time of entry and release. The liquid is the sum of the diluent and the experimental liquid, and the experimental liquid includes the standard solution and the sample.

[0025] The dilution assembly 11 includes a dilution drive 5, a dilution valve 17, and a diluent storage unit 12. The dilution valve 17 connects the dilution drive 5, the suction nozzle 8, and the diluent storage unit 12. The dilution valve 17 is used to control the flow direction of the diluent, and the diluent storage unit 12 is used to store the diluent. In some embodiments, the dilution drive 5 is a diluent suction pump. The dilution drive 5 draws the diluent into the pump body of the dilution drive 5 through the movement of the pump body and the suction nozzle 8. Meanwhile, the dilution valve 17 can be, but is not limited to, a solenoid valve. The dilution valve 17 is used to control the specific volume of the diluent entering the dilution drive 5 and the time of entry and release.

[0026] The separation component 10 and the dilution component 11 dilute and prepare the experimental liquid through the spray nozzle 8. The separation component 10 and the dilution component 11 share a set of spray nozzle 8 for the release and suction of the diluent and the experimental liquid. This configuration integrates the separation component 10 and the dilution component 11, solving the problem of low utilization rate caused by the need for additional equipment for the preparation of standard solutions in the background technology. It enables the gradient dilution of the experimental liquid to be completed on a single instrument, avoiding the waste of additional equipment. The separation component 10 and the dilution component 11 are connected to the spray nozzle 8 through pipelines.

[0027] like Figure 2 As shown, Figure 2 This is a schematic diagram of another control method for the diluent of this application. The control method for diluent 1 of this application includes: S100: (1) Insert the spray suction component 8 into the first liquid storage space; S101: (2) Open the liquid separator valve 18 so that the direction of the experimental liquid flow is from the spray suction device 8 toward the liquid separator drive device 2, and quantitatively draw the experimental liquid in the first liquid storage space into the liquid separator drive device 2. S102: (3) Transfer the spray suction component 8 to the second liquid storage space; S103: (4) Open the liquid separator valve 18 so that the experimental liquid flows from the liquid separator drive 2 toward the spray suction 8 and releases the experimental liquid in the liquid separator drive 2 into the second liquid storage space through the spray suction 8. S104 (5) Open the dilution valve 17 to connect the dilution liquid storage device 12 and the dilution drive device 5, and quantitatively draw the dilution liquid from the dilution liquid storage device 12 into the dilution drive device 5; S105: (6) Switch the dilution valve 17 to connect the dilution drive 5 and the spray suction 8, and release the diluent in the dilution drive 5 into the second liquid storage space through the spray suction 8, thereby completing the dilution.

[0028] In some embodiments, a first liquid storage space is provided in the first liquid storage device, and a second liquid storage space is provided in the second liquid storage device; the first liquid storage device may be provided with one or more first liquid storage spaces, which are not limited in number, and their function is to store experimental liquids, which may be, but are not limited to, samples; the second liquid storage device may be provided with one or more second liquid storage spaces, which are not limited in number, and their function is to store diluents and / or experimental liquids.

[0029] The spray suction component 8 is placed in the first liquid storage space to draw the experimental liquid in the first liquid storage space. When the spray suction component 8 enters the first liquid storage space, the liquid distribution valve 18 is opened. At this time, the opening direction of the liquid distribution valve 18 is from the spray suction component 8 toward the liquid distribution drive component 2. The amount of experimental liquid drawn can be quantitatively set through the liquid distribution valve 18 to meet specific experimental requirements. When the liquid distribution drive component 2 draws the experimental liquid, the pump body of the liquid distribution drive component 2 draws the experimental liquid through the spray suction component 8 into the pump body of the liquid distribution drive component 2.

[0030] The second liquid storage space is a dilution tube. The spray suction component 8 can be transferred into the second liquid storage space through a sliding structure such as a slide rail. After the spray suction component 8 enters the second liquid storage space, the liquid distribution valve 18 is opened. At this time, the pump body in the liquid distribution drive component 2 is pushed out, and the experimental liquid in the liquid distribution drive component 2 is released into the second liquid storage space through the spray suction component 8.

[0031] After the liquid separation assembly 10 completes the transfer and release of liquid, the dilution assembly 11 is activated, and the dilution valve 17 is opened. In some embodiments, the dilution valve 17 is a three-way valve, connected to the dilution drive unit 5, the spray suction unit 8, and the diluent storage unit 12 via pipelines. The dilution valve 17 is opened from the diluent storage unit 12 toward the dilution drive unit 5. At this time, the pump body in the dilution drive unit 5 draws inward, and the diluent in the diluent storage unit 12 flows into the dilution drive unit 5 through the dilution valve 17. At the same time, the dilution valve 17 can also be quantitatively set to draw the amount of diluent to meet specific experimental requirements. Then, the dilution valve 17 is opened from the liquid separation drive unit 2 toward the spray suction unit 8, and the diluent in the dilution drive unit 5 is released into the second storage space through the spray suction unit 8, thereby completing the dilution.

[0032] like Figure 3 As shown, Figure 3 This is a schematic diagram of another control method for the diluent of this application. Another control method for the diluent 1 of this application includes: S200: (1) Insert multiple suction components 8 into the first liquid storage space; S201: (2) Open multiple liquid dispensing valves 18 to make the experimental liquid flow from the spray suction device 8 toward the liquid dispensing drive device 2. According to the experimental requirements set by the multiple liquid dispensing valves 18, the liquid is drawn into the corresponding liquid dispensing drive device 2 by the multiple spray suction devices 8. After one of the multiple suction components 8 completes the suction of the set amount of experimental liquid, it waits for the other suction components 8 that have not yet completed the suction work to suction the experimental liquid until the preset number of suction components 8 complete the suction work. S202: (3) Insert multiple suction components 8 into the second liquid storage space; S203: (4) Open multiple liquid dispensing valves 18 to make the experimental liquid flow from the liquid dispensing drive 2 toward the spray suction 8, and release the experimental liquid in the multiple liquid dispensing drive 2 into the second liquid storage space through the multiple spray suction 8. S204: (5) Open multiple dilution valves 17 and connect the dilution liquid storage unit 12 and the dilution drive unit 5 to quantitatively draw the dilution liquid from the dilution liquid storage unit 12 into the multiple dilution drive units 5; S205: (6) Open multiple dilution valves 17 and connect multiple dilution drive components 5 and multiple spray suction components 8 to release the diluent in the multiple dilution drive components 5 into the second liquid storage space through the spray suction components 8, thereby completing the dilution.

[0033] In this method, the diluent 1 is equipped with multiple sets of spray-suction components 8, liquid dispensing components 10, and dilution components 11. The number of dilution driving components 5 and dilution valves 17 matches the number of spray-suction components 8, the number of liquid dispensing valves 18 and liquid dispensing driving components 2 matches the number of spray-suction components 8, and the number of second liquid storage spaces matches the number of spray-suction components 8. That is, one liquid dispensing component 10 and one dilution component 11 are connected to the same spray-suction component 8, forming a dilution and liquid dispensing mechanism. The diluent 1 can be equipped with multiple sets of dilution and liquid dispensing mechanisms. Simultaneously, because the first liquid storage space stores the experimental liquid, it can be one or more liquid storage spaces. Multiple second liquid storage spaces require separate dilution, therefore, the multiple second liquid storage spaces are different liquid storage spaces. This allows the first liquid storage space and the multiple second liquid storage spaces to accommodate multiple spray-suction components 8. In this application, "multiple" refers to a quantity of two or more, and the quantity of multiple components is the same in the same method flow.

[0034] In step (2), multiple different dispensing valves 18 can be set to absorb the amount of experimental liquid according to experimental requirements. The amount of experimental liquid absorbed by different dispensing valves 18 can be flexibly set, so that multiple experimental liquids with different requirements can be absorbed simultaneously, saving time and costs. After the multiple dispensing valves 18 are opened, multiple dispensing drive units 2 absorb the experimental liquid in the first storage container according to the setting of their matching dispensing valves 18. When one of the multiple aspiration units 8 has absorbed the set amount of experimental liquid, the dispensing valve 18 is closed, and the other aspiration units 8 that have not yet completed their aspiration work are waited to absorb the experimental liquid. After all the aspiration units 8 have completed their aspiration work, the multiple aspiration units 8 are transferred to multiple second storage spaces. The multiple aspiration units 8 and the multiple second storage spaces correspond one-to-one, so that the experimental liquid in each dispensing drive unit 2 can be released individually. If the diluent is equipped with multiple aspiration units 8, some of the aspiration units can be preset to work, so that the overall dilution process is flexible and controllable.

[0035] After the multiple dispensing components 10 complete their work, the multiple dilution components 11 begin to operate. At this time, the dilution valve 17 is opened from the diluent reservoir to the dilution drive component 5. Because the dilution valve 17 is a three-way valve, it is directly connected to the diluent reservoir 12 through a pipeline. Therefore, the diluent in the diluent reservoir can be directly introduced into the multiple dilution drive components 5 through the pipeline. There can be one or more diluent reservoirs 12, which can be flexibly set according to user requirements. The amount of diluent drawn by the multiple different dilution valves 17 can be set according to experimental requirements, and the amount of diluent drawn by different dilution valves 17 can be flexibly set.

[0036] By employing an array of solenoid valves for independent multi-channel control, the diluent 1 can batch-process different volumes of liquids without the need for individual tube processing, significantly improving work efficiency and resolving the low efficiency issue of differentiated proportioning in traditional methods. Multi-channel parallel operation avoids manual intervention and tube-by-tube processing, effectively eliminating the risk of contamination and improving operational reliability. Precise control of the pump stroke and set volume of the dispensing drive 2 and dilution drive 5 ensures accurate quantitative aspiration and release of experimental liquids and diluents, reducing measurement errors and improving the accuracy and repeatability of the dilution process.

[0037] like Figure 4 As shown, Figure 4 This is a schematic diagram of another control method for the diluent of this application. Another control method for the diluent 1 of this application includes: S300: (1) Insert the spray suction component 8 into the first liquid storage space; S301: (2) Open the liquid separator valve 18 so that the experimental liquid flows from the spray suction device 8 toward the liquid separator drive device 2, and quantitatively draw the experimental liquid in the first storage space into the liquid separator drive device 2. S302: (3) While the liquid separation component 10 is absorbing the experimental liquid, or after the liquid separation component 10 is absorbing the experimental liquid, open the dilution valve 17 to connect the dilution liquid storage 12 and the dilution drive 5, and quantitatively draw the dilution liquid from the dilution liquid storage 12 into the dilution drive 5. S303: (4) Transfer the spray suction component 8 to the second liquid storage space; S304: (5) Open the liquid separator 18 so that the experimental liquid flows from the liquid separator 2 toward the spray suction 8 and releases the experimental liquid in the liquid separator 2 into the second liquid storage space through the spray suction 8. S305: (6) At the same time as the liquid separation component 10 releases the experimental liquid, or after the liquid separation component 10 releases the experimental liquid, the dilution valve 17 is opened to connect the dilution drive 5 and the spray suction component 8, and the diluent in the dilution drive 5 is released to the second liquid storage space through the spray suction component 8, thereby completing the dilution.

[0038] This method and Figure 2The difference in method lies in that, simultaneously with the liquid separation drive 2 drawing in the experimental liquid, or after the liquid separation drive 2 drawing in the experimental liquid but before the spray suction component 8 is transferred to the second liquid storage space, the diluent is drawn into the dilution drive 5. This setup not only allows for the simultaneous release of the diluent and the experimental liquid, but also further reduces the dilution time required by the diluent 1, improving dilution efficiency. Other detailed procedures are the same as... Figure 2 The steps are the same, so they will not be repeated here.

[0039] like Figure 5 As shown, Figure 5 This is a schematic diagram of other control methods for the diluent of this application. The diluent 1 of this application also includes a method comprising: S400: (1) Insert multiple suction components 8 into the first liquid storage space; S401: (2) Open multiple liquid dispensing valves 18 to make the experimental liquid flow from the liquid dispensing drive 2 toward the spray suction 8. According to the experimental requirements set by the multiple liquid dispensing valves 18, the experimental liquid is drawn into the corresponding liquid dispensing drive 2 through the multiple spray suction 8. After one of the multiple suction components 8 completes the suction of the set amount of experimental liquid, it waits for the other suction components 8 that have not yet completed the suction work to suction the experimental liquid until the preset number of suction components 8 complete the suction work. S402: (3) While the liquid separation component 10 is absorbing the experimental liquid, or after the liquid separation component 10 is absorbing the experimental liquid, open multiple dilution valves 17 to connect the dilution liquid storage component 12 and the dilution drive component 5, and quantitatively draw the dilution liquid from the dilution liquid storage component 12 into the multiple dilution drive components 5. S403: (4) Insert multiple suction components 8 into the second liquid storage space; S404: (5) Open multiple liquid dispensing valves 18 to make the experimental liquid flow from multiple liquid dispensing drive components 2 toward multiple spray suction components 8, and release the experimental liquid in the multiple liquid dispensing drive components 2 into the second liquid storage space through multiple spray suction components 8. S405: (6) At the same time as the liquid separation component 10 releases the experimental liquid, or after the liquid separation component 10 releases the experimental liquid, multiple dilution valves 17 are opened, and the diluent in the multiple dilution drive component 5 is released to the corresponding second liquid storage space through the multiple spray suction component 8 from the direction of the dilution drive component 5 to the spray suction component 8, thereby completing the dilution.

[0040] This method is Figure 4The method for using multiple dilution components 11 includes the following: "After one of the multiple aspirators 8 completes the aspiration of the set amount of experimental liquid, waits for the other aspirators 8 that have not yet completed their aspiration work to aspirate the experimental liquid until all aspirators 8 have completed their aspiration work." This step can be set between steps (2) and (4), with the time it takes for the dilution components 11 to aspirate the diluent used as the order for judgment. Other step details are as follows: Figure 2 and Figure 3 The method is the same, so it will not be repeated here.

[0041] like Figure 6 and Figure 7 As shown, Figure 6 yes Figure 3 A schematic diagram of the control method for the mixing component of the diluent in this embodiment. Figure 7 yes Figure 5 The flowchart illustrates the control method of the mixing component in the diluent 1. The diluent 1 further includes a mixing component, which comprises a mixing drive and a mixing element. The mixing drive drives the mixing element to perform mixing. The number of mixing elements matches the number of second liquid storage spaces. In some implementations, the mixing drive in the mixing component can be an air pump or a motor, and the mixing element can be a mixing needle or a stirring rod. For example, an air pump can be used as the mixing drive, and a mixing needle can be used as the mixing element for air mixing, or a motor can be used to drive a stirring rod to rotate within the second liquid storage space to achieve mechanical mixing. The number of mixing elements matches the number of second liquid storage spaces to ensure that each second liquid storage space, such as a standard solution tube or a dilution tube, can be mixed independently, avoiding cross-contamination and operational interference during the mixing process.
