Description
High-Grade Silver Ore CRM for XRF Verification & QA/QC
The Alloy Geek Silver Ore Certified Reference Material – 6,741 ppm Ag is a high-concentration silver-bearing ore reference material designed for verification, validation, and ongoing quality control of both handheld and benchtop XRF spectrometers.
This CRM represents a real, mineralized silver-rich ore matrix, making it ideal for users who require matrix-appropriate performance checks rather than synthetic or pressed metal standards. It is especially well suited for precious-metal analysis, mining and geochemistry, concentrate verification, and high-Ag calibration range validation.
Certified Silver Concentration
- Silver (Ag): 6,741 ppm
- Certification based on multi-laboratory consensus using classical fire assay and instrumental methods
- Certified on a dry sample basis for precious metals
This concentration places the material squarely in the “rich silver ore / concentrate” range, making it ideal for:
- Upper-range silver linearity checks
- Drift verification on Ag-focused XRF methods
- Cross-checking laboratory or field XRF results against a certified benchmark
Typical Chemical Composition (Selected Major & Pathfinder Elements)
This CRM contains a complex sulphide-rich ore matrix representative of real mineralized material, including:
| Element | Certified Value |
|---|---|
| Silver (Ag) | 6,741 ppm |
| Copper (Cu) | ~16.4 wt.% |
| Lead (Pb) | ~8.3 wt.% |
| Zinc (Zn) | ~19.8 wt.% |
| Gold (Au) | ~63.7 ppm |
| Iron (Fe) | ~14.8 wt.% |
| Sulfur (S) | ~29 wt.% |
Numerous additional trace and minor elements are characterized, making this CRM highly valuable for multi-element XRF validation across complex ore matrices
Designed for XRF Applications
This certified reference material is suitable for:
✔ Handheld XRF Analyzers
- Field verification of silver response
- Drift and repeatability checks
- Precious-metal screening workflows
- Mining, exploration, and concentrate evaluation
✔ Benchtop & Laboratory XRF Systems
- Method validation
- Instrument qualification
- QA/QC charting
- Inter-instrument comparison
Because the material is a natural ore/concentrate, it behaves similarly to real samples during XRF excitation, making it especially valuable for matrix-matched verification.
Physical Form & Preparation
- Finely milled, homogeneous powder
- Sulphide-bearing silver-rich ore matrix
- Packaged for long-term stability
- Suitable for sample cups, pressed pellets, or loose-powder XRF analysis
Why Use an Alloy Geek Certified Reference Material?
- Real-world ore matrix (not synthetic)
- High-silver concentration ideal for upper-range checks
- Independently certified values
- Excellent homogeneity for repeatable measurements
- Optimized for both handheld and benchtop XRF workflows
This CRM is an excellent choice for customers who want confidence in their silver measurements, especially at elevated ppm levels where instrument performance matters most.
