A single-crystal X-ray diffractometer reveals 3D atomic structure by analyzing X-ray diffraction patterns (Bragg's Law). Through data collection, Fourier transformation, and model refinement, it generates electron density maps to determine molecular configurations.

This guide details XAS experiment design, emphasizing uniform sample preparation (e.g., grinding, dilution, inert handling) and precise measurement control (e.g., scan ranges, beam parameters, data averaging). Proper execution ensures reliable data on local atomic structure, vital for catalysis and energy materials research.

XAS, an advanced synchrotron-based technique, analyzes X-ray absorption to reveal atomic-scale local electronic states and geometric structures (via XANES and EXAFS) nondestructively, widely used in materials and energy research.

A quality single crystal for X-ray diffraction requires optimal solvent choice (moderate solubility/volatility), proper growth method (evaporation/diffusion), high sample purity, and a vibration-free environment to ensure well-defined morphology and minimal defects.

This article details a comprehensive three-pronged strategy to eliminate higher-order diffraction interference in X-ray single-crystal analysis. The methods involve hardware filtration at the source using monochromators and slits, parameter optimization during data collection to suppress detection, and software correction algorithms for residual effects in data processing. This combined approach ensures high-precision crystal structure determination by controlling intensity errors.

XRD analyzers use Bragg's Law to measure diffraction angles, enabling non-destructive decoding of crystal phases, lattice constants, grain size, and stress from interplanar spacing changes.

New-generation HR-XRD cuts energy use via hardware upgrades, smart controls, and full lifecycle management, maintaining precision while slashing costs and emissions for green labs.

This guide details essential maintenance for benchtop XRD systems, covering X-ray generation, optics, detectors, and safety. Regular upkeep ensures accuracy, prevents failures, and extends equipment life. The TDM-20 Benchtop XRD from Dandong Tongda Technology meets all your analytical needs.

XRD maintenance follows "Prevention First, Regular Inspection." Safety protocols require "Protection Priority, Standardized Procedures." Key practices include environment control, component care, strict safety checks, and proper shutdown. Adherence ensures instrument longevity, operator safety, and data reliability.

Benchtop diffractometers enable rapid, on-site phase identification. Their compact size and simple operation overcome traditional XRD limitations, boosting efficiency in QC, R&D, and field applications like material screening and analysis.

Powder diffractometer efficiency can be doubled by optimizing sample preparation (grinding, loading), instrument parameters (scan range/speed), and adopting batch processing and routine maintenance. These steps ensure high-quality data while significantly reducing experimental time and rework.
