TD-3700 XRD: Key Steps & Safety Procedure: Startup prep, calibration, sample loading, scanning, data analysis. Safety: Trained operators only. Wear full protective gear (dosimeter, lead glasses). Never open door during operation. Maintain clean, stable environment. Follow strict maintenance and emergency protocols.

Enhance resolution by upgrading to a high-resolution detector, optimizing crystal quality, employing precise data collection strategies, utilizing advanced software, and ensuring regular instrument maintenance.

XRD maintenance requires strict environmental control (temperature, humidity), regular cooling system care, and X-ray tube upkeep. Key troubleshooting includes resolving high voltage startup, shutter operation, goniometer errors, and cooling water alarms to ensure instrument stability and data accuracy.

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.

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.

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.

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.
