D-POWER X-ray Diffractometer (XRD) Series by GKINST

Overview

The D-POWER X-ray Diffractometer (XRD) Series by GKINST is a high-performance, floor-standing powder X-ray diffractometer engineered for precision phase identification, quantitative phase analysis, crystallite size determination, and lattice strain evaluation. Based on Bragg’s law and monochromatic X-ray diffraction principles, the system utilizes Cu, Mo, Co, Cr, or Fe anode X-ray tubes to generate characteristic Kα radiation, enabling robust structural characterization of crystalline and semi-crystalline materials. Its θ/θ goniometer architecture—featuring horizontal sample mounting—ensures optimal beam geometry, mechanical stability, and operator accessibility. With a standard goniometer radius of 245 mm (continuously adjustable from 225 mm to 395 mm), the instrument supports both high-resolution scanning and rapid data acquisition across a wide angular range (–110° to +168° 2θ), making it suitable for both fundamental research and routine quality control in regulated industrial environments.

Key Features

• High-power X-ray source: 3 kW high-frequency generator with programmable voltage (2–60 kV, 1 kV/step) and current (2–50 mA, 1 mA/step) for flexible excitation conditions.
• Precision goniometry: Vertical θ/θ configuration with angular resolution down to 0.0001°, repeatability ±0.0001°, and absolute angular accuracy ≤ ±0.01° — critical for Rietveld refinement and microstructural parameter extraction.
• Optimized optical path: Motorized variable divergence slits (0.05–6 mm), automatic anti-scatter blades (0.05–25 mm), and selectable focal spot geometries (line focus: 12 mm × 0.04 mm; point focus: 1.2 mm × 0.4 mm) ensure optimal intensity-to-resolution balance.
• One-dimensional array detector with energy-resolved photon counting: 678 eV RMS energy resolution enables effective background suppression and enhanced peak discrimination in complex spectra.
• Robust mechanical architecture: Floor-standing design (1029 mm × 1350 mm × 1955 mm; ≤1000 kg) with integrated cooling system (max. water pressure 0.7 MPa; flow rate 3.5 L/min) ensures thermal stability during extended acquisitions.

Sample Compatibility & Compliance

The D-POWER accommodates standard powder holders (glass, silicon, zero-background single-crystal Si), capillary mounts, thin-film stages, and optional environmental cells (e.g., heating, humidity, gas-controlled chambers). Its modular sample stage design supports ISO 13320-compliant particle size distribution analysis via XRD line-broadening methods and ASTM E975-22 for residual stress measurement in metallic components. The system meets general electrical safety requirements per IEC 61010-1 and electromagnetic compatibility standards (IEC 61326-1). While not pre-certified for FDA 21 CFR Part 11, its software architecture supports audit-trail-enabled operation when deployed under validated laboratory workflows aligned with GLP/GMP practices.

Software & Data Management

The instrument is operated via GKINST’s proprietary XRD Analysis Suite, a Windows-based platform supporting real-time data acquisition, automated calibration (including internal standard correction), phase identification using ICDD PDF-4+ database integration, and full-profile Rietveld refinement (via embedded GSAS-II engine). Raw data are stored in industry-standard .raw/.xye formats; processed reports include metadata logging (operator ID, timestamp, instrument parameters, calibration history) to support traceability. Batch processing, spectral overlay, and export to CSV, CIF, and PDF formats are natively supported. Optional API modules enable integration with LIMS and enterprise data systems through secure RESTful endpoints.

Applications

The D-POWER XRD system delivers reliable performance across diverse sectors requiring crystalline phase analysis: semiconductor process development (thin-film thickness and stress mapping), battery cathode/anode material characterization (e.g., layered oxide phase purity, Li-site occupancy), cement hydration kinetics monitoring, metallurgical QC (phase fraction quantification in steels and superalloys), mineralogical identification in geoscience and petroleum exploration, pharmaceutical polymorph screening per USP , food authenticity verification (e.g., starch crystallinity, adulterant detection), and environmental solid-phase speciation (e.g., heavy metal-bearing mineral phases in soils and sediments).

FAQ

What X-ray tube anodes are supported?
Cu, Mo, Co, Cr, and Fe anodes are available; tube selection is determined by required wavelength, absorption edge considerations, and sample matrix composition.
Is the goniometer radius adjustable during operation?
Yes—the scan radius is motorized and continuously tunable between 225 mm and 395 mm without manual intervention, enabling dynamic optimization of resolution vs. intensity trade-offs.
Does the system support in situ or operando measurements?
Standard configurations support ambient temperature/pressure analysis; optional accessories include furnace stages (up to 1200°C), cryo-coolers (down to 10 K), and gas-tight reaction cells for time-resolved studies.
What level of software validation support is provided?
GKINST supplies IQ/OQ documentation templates, electronic signature-ready report generation, and configurable user access levels—enabling laboratories to perform their own PQ and maintain compliance with ISO/IEC 17025 or internal SOPs.
How is detector energy resolution utilized in practice?
The 678 eV RMS energy resolution allows discrimination between fluorescence peaks and diffraction signals, significantly improving signal-to-background ratio in samples containing high-Z elements (e.g., catalysts with Pt, Ni, or Co additives).
