In 2013, Dandong Tongda Technology Co., Ltd. became the undertaking unit of the single crystal X-ray diffractometer project of the National Ministry of Science and Technology [National Major Scientific Instrument Development Special Project]. Officially sold in 2020, the TD-5000 single crystal X-ray diffractometer fills the domestic gap, meets the needs of domestic users, and is also exported to the United States, Pakistan, Azerbaijan and other countries. Now let's take a closer look at the TD-5000 X single crystal diffractometer

X-ray single crystal diffractometer is mainly used to determine the three-dimensional space structure and electron cloud density of inorganic, organic and metal complexes and other crystal materials, as well as to analyze the structure of special materials such as twins, incommensurable crystals and quasicrystals. Determine the exact three-dimensional space (including bond length, bond angle, configuration, conformation and bonding electron density) of the new compound (crystal) molecule and the actual arrangement of the molecule in the crystal lattice were determined. It can provide crystal cell parameters, space group, crystal molecular structure, hydrogen bond and weak interaction information, molecular configuration and conformation information. It is widely used in chemical crystallography, molecular biology, pharmacology, mineralogy and material science.

1.PILATUS mixed pixel detector

The PILATUS hybrid pixel detector provides the best data quality while ensuring low power consumption and low cooling. The detector combines the two key technologies of single photon counting and mixed pixels, it is used in various fields such as synchrotron radiation and conventional laboratory light source, effectively eliminate the interference of reading noise and dark current, hybrid pixel technology can detect X-rays directly, easier to resolve the signal, and the PILATUS detector can efficiently provide high quality data.

2.Goniometer

The four-circle concentric technology is used to ensure that the goniometer center remains unchanged regardless of any rotation, achieving the purpose of obtaining the most accurate data. To obtain higher integrity, the four circles concentricity is a necessary condition for conventional single crystal scanning.

3.Cryogenic equipment

The data collected through the cryogenic equipment has more ideal results, and under the action of the cryogenic equipment, more advantageous conditions can be improved, which may make the imperfect crystal obtain ideal results. The ideal crystal can also obtain more ideal results.

Temperature control range: 100K~300K

Control accuracy: ±0.3K

Liquid nitrogen consumption: 1.1~2L/H

4.Perfect control software and test results

The control software is independently developed and has set multiple collection strategies, fully automatic scanning, independently judging the collision relationship of each axis, returning images in real time, calculating d value, the nickel wire diffraction ring automatically calibrates the center of the optical path, switches the double target and automatically adapts the zero point of the goniometer, calculates the distance from the sample to the detector through the image, and automatically adapts the image intensity and color.
