[0031] Embodiment 1

[0032] Please refer to Figure 1-4 , an atomic absorption spectrometer, comprising:

[0033] Atomic absorption spectrometer body 1, atomic absorption spectrometer body 1 model is LabAA 2000. When in use, the sample to be tested is subjected to appropriate pretreatment, including dissolution, dilution, heating and vaporization, etc., so that the target element in the sample exists in the form of atoms and is stored in the detection chamber of the atomic absorption spectrometer body 1. Then, a light source of a specific wavelength is selected, usually a hollow cathode lamp, and the wavelength matches the specific absorption line of the element to be tested. The light emitted by the light source is filtered and adjusted by optical devices such as gratings or filters to obtain the required wavelength and light intensity. After the sample is atomized, the atomic absorption spectrometer body 1 guides the excitation light to the sample pool through the optical path to interact with the sample. The target element atoms in the sample will absorb the light of a specific wavelength, and the intensity of the absorbed light is positively correlated with the concentration of the target element in the sample. The photoelectric detector can be used to measure the intensity of the light absorbed in the sample pool and convert it into an electrical signal. The atomic absorption spectrometer body 1 amplifies and filters the electrical signal output by the photoelectric detector, and then compares it with a blank sample to eliminate the influence of background absorption. Calibration and quantitative analysis are performed according to the standard curve or a standard sample of known concentration, so as to obtain the concentration value of the target element in the sample. Finally, a corresponding report or data is generated according to the analysis results.

[0034] Both sides of the atomic absorption spectrometer body 1 shell are provided with mounting grooves 2, and a handle 3 is rotatably installed in the mounting groove 2. The handle 3 is provided to facilitate two people to carry the atomic absorption spectrometer body 1, and when the handle 3 is not in use, the handle 3 is stored in the mounting groove 2 without occupying space.

It does not require multiple staff members to assist in the movement for position adjustment. It is easy to use. After arriving at the target location, the moving plate 7 is driven upward by the electric push rod 6, so that the universal wheel 8 is retracted back into the moving seat 4, and the moving seat 4 is firmly supported again to avoid accidental movement.

[0036] The four corners of the top of the moving plate 7 are fixedly provided with telescopic sleeves 11, and the telescopic range of the telescopic sleeves 11 is consistent with the telescopic range of the electric push rod 6. The other ends of the four telescopic sleeves 11 are fixedly connected to the top of the inner wall of the moving seat 4. During the telescopic process of the output end of the electric push rod 6, the four telescopic sleeves 11 are contracted synchronously to ensure that the four corners of the moving plate 7 are evenly stressed, thereby ensuring the stability of the moving plate 7 during the up and down movement;

[0037] The buffer assembly is arranged on the universal wheel 8 and is used to buffer the jitter during the movement of the mobile seat 4, so as to protect the atomic absorption spectrometer body 1. The buffer assembly includes a damping column 9 and a buffer spring 10 fixedly arranged on the top of the universal wheel 8. The buffer spring 10 is sleeved on the damping column 9. The other ends of multiple groups of damping columns 9 and buffer springs 10 are fixedly connected to the bottom of the moving plate 7. The jitter generated during the movement of the atomic absorption spectrometer body 1 is absorbed by the damping column 9 and the buffer spring 10, which helps to protect the electrical components inside the atomic absorption spectrometer body 1 from damage.
