Benchtop XRD performance depends on instrument resolution (FWHM <0.04°2θ), goniometer linearity (±0.02°2θ), and low-angle ability. Sample form, size, and quantity matter. Voltage, current, scan speed/range, and method are key settings. Cooling, lab environment, and maintenance ensure stability and accuracy.

To maintain accuracy and stability in desktop X-ray diffractometers, regular calibration using standards like silicon and environmental controls (temperature, humidity, cleanliness) are essential. Proper maintenance, stable power supply, operator training, and timely updates further ensure reliable long-term performance and data integrity.

Benchtop X-ray Diffractometers are vital for quality control, providing non-destructive, precise analysis of material crystal structure, composition, and stress. They enable defect detection, process optimization, and failure analysis across R&D and production, enhancing efficiency, reliability, and compliance.

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.
