Dandong Tongda Technology Rotating Sample Stage: A Precision Rotation Partner for X-Ray Diffraction Analysis

In the fields of materials science and industrial testing, precise sample analysis relies on reliable instruments. The rotating sample stage produced by Dandong Tongda Technology Co., Ltd. is precisely such a critical accessory dedicated to enhancing the quality of X-ray diffraction (XRD) analysis. In X-ray diffraction analysis, the characteristics of the sample itself often pose challenges. For example, when the grains are excessively coarse, the material exhibits significant texture (or "preferred orientation," meaning the grains are not randomly arranged), or the sample has specific crystal habits (crystal growth patterns), obtaining diffraction data that is statistically representative and truly reflects the overall material properties becomes difficult. When measuring such samples with traditional static sample stages, the diffraction intensity may be distorted due to the aforementioned factors, affecting the accuracy of phase identification, texture analysis, and other evaluations. The core design philosophy of Tongda Technology's rotating sample stage is to address these challenges by enabling smooth rotation of the sample within its own plane. Core Function: Eliminating Orientation Errors and Enhancing Data Reliability The working principle of this rotating sample stage is intuitive and effective. By driving the sample to rotate continuously or in a stepwise manner, it ensures that the X-ray beam covers more grains with different orientations on the sample during irradiation. The main advantages of this approach are: Effective Reduction of Measurement Errors: Through the rotation averaging effect, it significantly mitigates measurement deviations caused by coarse grains or preferred orientation, making the diffraction data more representative of the material's overall properties. Ensuring Result Reproducibility: Whether the sample itself has texture or not, it guarantees good reproducibility of diffraction intensity across multiple measurements or between different laboratories, enhancing the reliability and comparability of data. Simplified Sample Preparation Requirements: It reduces the stringent demands for perfect sample preparation to a certain extent, improving analysis efficiency. Technical Specifications: Precision Control and Flexible Adaptability The rotating sample stage from Dandong Tongda Technology offers the following key technical parameters to meet the rigorous demands of scientific research and industrial testing: ParameterDescription Rotation Methodβ-axis (sample rotates within its own plane) Rotation Speed Range1 ~ 60 RPM (revolutions per minute) Adjustable based on experimental requirements Stepping PrecisionMinimum step width: 0.1º Supports high-precision positioning scanning Operation ModesConstant-speed rotation (for sample scanning), stepping, continuous, and other modes Adapts to various testing workflows and data acquisition needs Typical ApplicationsQuality control and R&D in industries such as environmental protection and electronics CompatibilityPrimarily used as an accessory for X-ray diffraction spectrometers (XRD) Application Scenarios: Serving the Environmental Protection and Electronics Industries This rotating sample stage is not merely a "showpiece" in the laboratory; it directly serves industries with high requirements for material analysis, such as environmental protection and electronics. In areas such as quality control, new product development, and failure analysis in these fields, it assists engineers and researchers in conducting more accurate phase analysis on samples of various forms, including powders, bulk materials, and thin films, ensuring the authenticity and reliability of data.

The Beauty of Technology in Dandong Tongda NDT Portable X-ray Welding Testing Machine

Non-Destructive Testing (NDT) is an indispensable quality assurance technology in modern industry. It enables the detection of internal defects, structures, and property conditions of materials by utilizing characteristics such as acoustic, optical, magnetic, and electrical properties—all without damaging or affecting the performance of the tested object. Compared to destructive testing, NDT has the following characteristics: First, it is non-destructive, as it does not impair the performance of the test object. Second, it is comprehensive. Since the testing is non-destructive, it allows for 100% full inspection of the test object when necessary, which is impossible with destructive testing. Third, it is full-process applicable. Destructive testing is generally only suitable for raw materials, such as tensile, compression, and bending tests commonly used in mechanical engineering. Destructive testing is conducted only on raw materials for manufacturing. For finished products and in-service equipment, destructive testing cannot be performed unless they are no longer intended for use. In contrast, NDT does not damage the test object’s performance, making it suitable for full-process testing, from raw materials and intermediate manufacturing stages to final products, as well as for in-service equipment. Among the many manufacturers of non-destructive testing equipment, Dandong Tongda Technology Co., Ltd. has developed a variety of NDT instruments that approach or achieve internationally advanced levels, thanks to its solid technical expertise and innovative capabilities. Technical Features: Portability, Safety, and Intelligence Tongda Technology's NDT Portable X-ray Welding Testing Machine exhibit several outstanding features.
