The TD-3500 is a high-performance X-ray diffraction analysis system developed by Dandong Tongda Technology Co., Ltd. It is widely used in materials science, chemistry, geology, and industrial quality control. The instrument enables precise crystal structure analysis, phase identification, grain size determination, and residual stress analysis for powder, bulk, and thin-film samples, providing reliable data support for scientific research and industrial inspection.

Core Competitive Advantages

Outstanding Stability and Reliability

The instrument’s core control system adopts a German Siemens industrial-grade programmable logic controller (PLC), replacing the traditional single-chip microcomputer architecture commonly used in XRD equipment. This design significantly enhances the instrument's anti-interference capability and operational stability, allowing it to maintain long-term, trouble-free operation under continuous high-load working conditions. It is particularly suitable for demanding application scenarios such as industrial on-site environments where equipment reliability is critical.

Top-Level Measurement Accuracy

The TD-3500 features a θ-θ vertical goniometer structure, combined with high-precision bearings and a fully closed-loop servo control system. This configuration achieves a minimum step angle control capability of 0.0001° and excellent angular reproducibility. The design not only simplifies sample placement but also effectively supports precise testing requirements for special samples such as liquids and loose powders.

High Degree of Intelligence and Ease of Use

The system is equipped with a true-color touchscreen operating interface, significantly improving the user experience through graphical interaction. The instrument integrates multiple automated functions, including an X-ray tube automatic training program, high-voltage soft-start/soft-shutdown protection mechanisms, and an intelligent fault diagnosis system. These features greatly reduce the technical barriers to equipment operation and maintenance complexity.

Strong Industry Application Validation

The instrument has gained widespread recognition in both domestic and international markets, particularly in the titanium dioxide (TiO₂) industry, where it has formed a mature solution. To meet the specific needs of this industry, the company has developed dedicated analysis software that enables precise determination of rutile-type titanium dioxide content, with measurement errors controllable within 0.2%. This meets the high-standard quality control requirements of the industry.

With its excellent stability, precise measurement capabilities, intelligent operational experience, and proven industry application results, the TD-3500 has become a trusted testing tool in the field of materials analysis. It is capable of providing accurate and efficient testing solutions for a wide range of users.
