XRD Reference Materials & Sample Preparation
Support reliable X-ray Diffraction (XRD) analysis with suitable specimen preparation, calibration standards, reference materials and quality-control practices for phase identification, crystallographic analysis and material characterization.
Typical Sample Types for XRD
The appropriate preparation and reference material depend on the crystalline phase, particle size, sample form, matrix and analytical objective.
Minerals & Geological Samples
Phase identification and mineralogical characterization of rocks, ores and geological powders.
Cement & Building Materials
Crystalline phase analysis for cement, clinker, raw meal and related construction materials.
Ceramics & Glass-Ceramics
Phase identification and structural analysis for ceramic and advanced inorganic materials.
Pharmaceutical Materials
Solid-form and phase characterization for selected pharmaceutical and raw-material applications.
Metals & Powder Metallurgy
Phase and structural analysis of metallic powders, alloys and processed materials.
Advanced Materials
Crystallographic and phase analysis for catalysts, battery materials and engineered solids.
Prepare the Specimen for Reliable Diffraction
XRD sample preparation focuses on representative sampling, suitable particle size, homogeneous packing and minimizing orientation or surface effects that may bias diffraction results.
Grind & Homogenize
Prepare a representative powder with suitable and consistent particle size for the intended method.
Control Orientation
Use a preparation approach that reduces preferred orientation where it can affect peak intensities.
Mount the Specimen
Prepare a flat and stable specimen surface with consistent sample height and packing density.
Verify Instrument Performance
Use an appropriate XRD reference material or standard to verify calibration and analytical performance.
How to Select the Right XRD Reference Material
Reference material selection should follow the intended XRD function, required metrological property, sample matrix and quality-control objective.
Define the Intended Use
Determine whether the material is needed for alignment, peak-position checks, resolution, phase analysis or QA/QC.
Match the Material Type
Select a crystalline reference material suitable for the measurement objective and instrument configuration.
Review Certified Properties
Confirm the certificate, assigned values and intended measurement use before routine implementation.
Verify Routine Performance
Use independent check materials or reference samples to monitor repeatability and instrument performance.
XRD Reference Material Options
Availability depends on the intended XRD function, certified property, matrix, instrument configuration and manufacturer portfolio.
