[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it individually or selectively refer to an embodiment that is mutually exclusive of other embodiments.

[0028] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0029] Example 1, with reference to Figure 1 - Figure 3 This is the first embodiment of the present invention, which provides a mobile chemical analysis laboratory device, including a housing 101 measuring 6000×3000×2800mm. Housing 101 is divided into a first compartment 102 on the left and right, a second compartment 103, and a transition compartment 104 in the middle. These three areas are connected by an access door. The second compartment 103 is the anion analysis area, primarily conducting anion liquid chromatography analysis. The first compartment 102 is the cation analysis area, primarily conducting atomic absorption cation analysis. The transition compartment 104 is a preparatory area for entering the first and second compartments 102 and 103, primarily used for changing clothes, configuring auxiliary equipment, and shielding from external influences. Each experimental area is equipped with a sample processing table 102a. The laboratory cabinet is 900mm high and 600mm wide. All experimental instruments are placed on the sample processing table 102a. The lower portion of the cabinet is equipped with a cabinet and a drawer for storing laboratory reagents, consumables, and other supplies.

[0030] The experimental area is equipped with a large analytical instrument fixing seat 102b, which is made of iron and has a heavy weight. Its main function is to provide stability and prevent the fixing seat 102b from sliding on the sample processing table 102a. Its weight and material help to keep the fixing seat 102b stable when the large instrument is placed or used. A track is provided on the fixing seat 102b. The slider 102b-1 is slidably connected in the track, so that the slider 102b-1 can move along the fixing seat 102b. In this way, the position of the slider 102b-1 can be adjusted to adapt to instruments of different sizes. There is a circular hole on the slider 102b-1, and a screw 102b-2 is movably connected in the circular hole. There are several fixing holes 102b-5 distributed in an array at the bottom of the inner wall of the track. The screw 102b-2 passes through the slider 102b-1 and is movably connected in the fixing hole 102b-5, and the screw 1 The bottom of 02b-2 is spherical, and the spherical shape helps the screw 102b-2 to automatically align with the fixing hole 102b-5, because the distance from any point of the sphere to the center of the sphere is equal, which makes it easier for the screw 102b-2 to find the center of the fixing hole 102b-5 when inserted. A limit plate 102b-4 is threadedly connected to the outside of the screw 102b-2 above the slider 102b-1. By rotating the limit plate 102b-4, its height can be adjusted to support large instruments. The design of the limit plate 102b-4 allows the user to adjust the support height as needed to accommodate instruments of different heights. The provision of multiple fixing seats 102b can provide all-round protection for large instruments and is used to fix large analytical instruments such as ion chromatographs to prevent large analytical instruments from sliding during transportation and use.

[0031] The experimental area is equipped with a demineralized water pipe 104d and a tap water pipe, with a water tank 102c located below. Below this tank 102c is a temporary water tank and water purifier, which can serve as a temporary water source to meet analytical water needs when external water is unavailable. The experimental area is also equipped with constant temperature and humidity air conditioning and dust-proof windows to ensure that the laboratory temperature and humidity range is 20% to 70%.

[0032] The transition area is provided with a box 101 door as a personnel entrance and exit passage, and an emergency material cabinet 104a is provided to store emergency materials for experiments. At the same time, a waste liquid collection box 104c is provided at the bottom of the cabinet. The water tank size is 1500×20×2000mm to collect waste water during the experiment. A liquid level gauge for the waste liquid collection box 104c is also provided in the transition area to monitor the waste liquid collection situation in real time.

[0033] Example 2, reference Figure 4 - Figure 7, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the sample separation unit 200 includes a sample separation body 201 and a sample receiver 202, the sample separation body 201 and the sample receiver 202 are arranged in the first section 102, a sample bottle 203 is arranged below the sample separation body, and a cleaning bottle 204 is arranged on one side of the sample bottle 203.

[0034] Furthermore, the rotating arms 201a are provided with several groups arranged in a rectangular array and evenly distributed on the sample divider body 201. This allows the sample divider body 201 to process multiple samples simultaneously, improving experimental efficiency and processing capacity. The sample divider needle 201b is rotatably connected to the lower end of the rotating arm 201a, and is used to directly contact the sample and perform the sample division operation to precisely control the distribution of the sample.

[0035] Storage chamber 201c includes a sealing piston 201c-1, a power rod 201c-2, a drive spring 201c-3, and an electric push rod 201c-4. These components work together to control the storage and release of samples. Sealing piston 201c-1 is positioned within storage chamber 201c, with its outer wall tightly fitting the inner wall. It controls the intake and discharge of samples by moving up and down within storage chamber 201c. When the piston moves upward, it expels air or sample from storage chamber 201c; when it moves downward, it draws in sample. Power rod 201c-2, the component that transmits power, has its lower end fixedly connected to sealing piston 201c-1. Power rod 201c-2 is shaped like an I, with disc-shaped upper and lower ends, and its diameter equal to that of sample dividing needle 201b. This allows the power rod 201c-2 to be tightly coupled with the sample needle 201b, ensuring efficient power transmission. The "I"-shaped structure also provides additional stability and support. The electric push rod 201c-4 is the power source for the entire system. Driven by a motor, it converts electrical energy into linear motion, thereby pushing the power rod 201c-2. A drive spring 201c-3 is provided between the electric push rod 201c-4 and the power rod 201c-2. This acts as a buffer and reset when the electric push rod 201c-4 pushes the power rod 201c-2. The drive spring 201c-3 absorbs some of the impact force and helps the power rod 201c-2 return to its initial position when the electric push rod 201c-4 stops working.

[0036] After the electric push rod 201c-4 receives the control signal, the motor starts working, pushing the power rod 201c-2 forward or backward. The movement of the power rod 201c-2 drives the sealing piston 201c-1 to move in the storage chamber 201c, thereby controlling the storage and release of the sample. When the sample needs to be released, the electric push rod 201c-4 pushes the power rod 201c-2 to make the sealing piston 201c-1 drop, and the sample is released through the needle 201c-5 of the sample dividing needle 201b. When the sample release needs to be stopped, the electric push rod 201c-4 stops working, and the driving spring 201c-3 helps the power rod 201c-2 and the sealing piston 201c-1 return to their initial positions.

[0037] Furthermore, the cleaning bottle 204 includes cleaning water 204a and dry air 204b, which are used to clean and dry the sample dividing needle 201b during the experiment to prevent cross contamination and ensure the purity of the sample.

[0038] During use, the electric push rod 201c-4 and the drive spring 201c-3 are used to move the sealing piston 201c-1 to the bottom of the storage chamber 201c so as to load the sample. The sample is injected into the storage chamber 201c until the sample fills the storage chamber 201c. The electric push rod 201c-4 is operated to make the sealing piston 201c-1 rise, close the opening of the storage chamber 201c, and ensure the sealing of the sample. The rotating arm 201a is rotated to move the sample needle 201b to the position where the sample needs to be distributed. The electric push rod 201c-4 is controlled to make the sealing piston 201c-1 descend, thereby pushing the sample through the needle 201c-5 of the sample needle 201b. When the needle 201c-5 of the sample needle 201b contacts the target container The device continues to control the sealing piston 201c-1 to descend, releases an appropriate amount of sample, and transfers the sample from the storage chamber 201c to the target position by precisely controlling the movement of the electric push rod 201c-4 and the sealing piston 201c-1. After the sampling operation is completed, immerse the sampling needle 201b in the cleaning water 204a in the cleaning bottle 204 for cleaning. Then, use the dry air 204b at the mouth of the cleaning bottle 204 to dry the sampling needle 201b to remove moisture and residue. Repeat the operation. If multiple samples need to be sampled, repeat the steps until all samples are correctly distributed. After completing all sampling operations, clean and dry the sampling needle 201b and the storage chamber 201c, and then store them in an appropriate location for next use.

[0039] The remaining structures are the same as those of Example 1.
