The rotating sample holder in an X-ray diffractometer is a key component used for precise adjustment and fixation of the sample position,the sample can rotate within its own plane, which is beneficial for errors caused by coarse grains. For samples with texture and crystallography, rotating sample holder ensures good reproducibility of diffraction intensity and eliminates preferred orientation. Working principle of rotating sample holder: When the X-ray diffractometer is working, high-energy X-rays generated by the X-ray source are irradiated onto the sample fixed on the rotating sample stage. Due to the specific crystal structure and lattice parameters of the sample, X-rays will undergo scattering, absorption, and diffraction phenomena when interacting with the sample, where diffraction phenomena occur according to the requirements of the Bragg equation. The rotating sample holder can rotate at smaller angles according to the setting, allowing the sample to receive X-ray irradiation at different angles, thereby obtaining diffraction patterns at different angles. In this way, the detector can measure the X-ray intensity after sample diffraction and convert it into an electrical signal to be transmitted to the computer for data processing. The main function of the rotating sample holder is: Rotation method: β axis (sample plane) Rotation speed: 1~60RPM Small step width: 0.1 º Operation mode: Constant speed rotation for sample scanning (step, continuous) Advantages of rotating sample holder: The rotating sample holder can improve the accuracy of diffraction data: For samples with irregular powder or particle shapes, the characteristic of preferred orientation is prone to occur during conventional powder sample preparation, resulting in deviations in the distribution of diffraction intensity and affecting the accuracy of diffraction result analysis. Rotating the sample stage can move the sample in a certain form in an appropriate space, eliminating the influence of preferred orientation to a certain extent, thereby improving the accuracy of diffraction data. The rotating sample holder can adapt to various testing needs: able to adapt to different types of X-ray diffraction angle measuring instruments, such as vertical angle measuring instruments, low-power compact powder diffraction equipment, etc., providing convenience for different testing needs. And rotating sample holder can meet the requirements of various samples and testing conditions by adjusting parameters such as speed and steering. The rotating sample holder can expand the instrument's analytical capabilities: New types of rotating sample stages are constantly being developed and applied, such as some sample stages for in-situ electrochemical X-ray diffraction analysis, which can monitor and analyze the changes of materials in different environments or conditions in real time, expanding the analysis capabilities of X-ray diffraction equipment. In summary, the rotating sample holder in X-ray diffractometer is crucial for accurately obtaining crystal structure information of substances. the rotating sample holder can not only improve the accuracy of diffraction data, but also adapt to various testing needs and expand the analytical capabilities of the instrument.
