The TD-5000 X-ray Single-Crystal Diffractometer is a high-performance instrument developed by Dandong Tongda Technology. Approved under China's National Key Scientific Instrument and Equipment Development Project, it fills a critical domestic gap in this field. Its primary function is determining the three-dimensional spatial structure and electron density distribution of crystalline substances—including inorganic compounds, organic compounds, and metal complexes—while also analyzing structures of special materials like twinned crystals, incommensurately modulated structures, and quasicrystals. It precisely measures the accurate 3D spatial structure of new crystalline compounds (including bond lengths, bond angles, configuration, conformation, and bonding electron density) and the actual arrangement of molecules within the crystal lattice. The system provides comprehensive structural information such as unit cell parameters, space group, molecular structure, intermolecular hydrogen bonding and weak interactions, and molecular configuration/conformation. It is widely used for analytical research in chemical crystallography, molecular biology, pharmacology, mineralogy, and materials science.

Core Technology: A Dual Revolution in Precision and Intelligence

(1) The "Mechanical Eye" with Atomic-Level Positioning

• Four-Circle Concentric Diffractometer: Overcomes traditional mechanical offset limitations, maintaining a constant rotational center to ensure diffraction spot coordinate errors remain below the nanometer level.

• PILATUS Detector: Combines single-photon counting technology with 172μm ultra-fine pixels. Achieves frame rates up to 20Hz, with noise suppression capability 3 times greater than conventional CCD detectors.

(2) Fully Intelligent Closed-Loop Workflow

• PLC One-Touch Control: Automates the entire process from crystal positioning to data acquisition, reducing manual operation time by 90%.

• Cryogenic Enhancement System: Features ±0.3 K precision temperature control (100K–300K), boosting signal intensity for weakly diffracting crystals by 50% with liquid nitrogen consumption of only 1.1–2 L/h.

(3) Dual Assurance: Safety and Expandability

• Lead Door Interlock + Leakage Protection (≤0.12 µSv/h), exceeding national safety standards.

• Optional Multilayer Focusing Optics (Mo/Cu Dual Target), enabling full-scale analysis from small-molecule pharmaceuticals to minerals with large unit cells.

The advent of the TD-5000 X-ray Single-Crystal Diffractometer signifies more than an instrumental breakthrough—it marks the era where China's high-end scientific research equipment officially achieves autonomous precision definition. As of 2025, this system has served over 30 leading institutions across fields including chemistry, materials science, and aerospace. As crystals unveil the secrets of life under the probing gaze of domestically developed instruments, China's scientific "eye that discerns the essence of matter" now shines with brilliant clarity.
