XRD Systems for Crystal Structure and Residual Stress Analysis — by GNR

X-ray diffraction (XRD) analyses the crystal structure and phases of materials without destroying the sample, in powder or solid form. Results are reported as diffraction angle 2θ according to Bragg’s law (nλ = 2d sinθ). Two Theta quotes XRD systems and residual-stress analyzers from GNR for materials research and the metals industry — choose a model to see its specifications and details.

How It Works

The Science of X-Ray Diffraction

X-ray diffraction is a non-destructive analytical technique that identifies and quantifies the crystalline phases present in solid materials and powders. Based on Bragg’s law, XRD provides clear phase identification, quantitative analysis and structural characterization — from routine quality control to advanced materials research.

  • Non-destructive — XRD leaves samples fully intact. Recover and reuse your specimens after analysis.
  • Qualitative and quantitative — Identify which phases are present and calculate their weight percentages using Rietveld refinement.
  • ICDD database — Match diffraction patterns against ICDD reference data to identify phases.
  • Powder and bulk solids — Analyze samples as loose powder, pressed pellets or cut solids.

Applications

What Can XRD Do for You?

Phase Identification

Identify and quantify crystalline phases in geological, industrial and pharmaceutical samples using ICDD database matching.

Crystal Structure

Determine unit cell parameters and structural data for novel compounds, minerals and synthesized materials.

Residual Stress

Measure residual and applied stresses in metals, ceramics and composites via the sin²ψ or cos α method.

Texture Analysis

Characterize preferred crystallographic orientation (texture/ODF) in rolled metals, thin films and geological specimens.

Pharmaceutical QC

Monitor polymorph content, crystallinity and amorphous fraction in active pharmaceutical ingredients and drug products.

Mining and Geology

Quantify ore mineralogy, clay content and gangue phases in drill core and process samples for grade control and process optimization.
