Description
High Concentration Silver-Bearing Ore CRM for XRF Verification & QA/QC
The Alloy Geek Silver Ore Certified Reference Material – 2,732 ppm Ag is a certified, silver-bearing polymetallic ore reference material designed for verification, validation, and routine quality control of both handheld and benchtop XRF spectrometers.
This CRM represents a real sulphide-rich concentrate matrix containing silver alongside copper, zinc, lead, and gold. It is ideal for users who need matrix-matched verification rather than synthetic standards—particularly in precious metals, mining, and metallurgical workflows.
Certified Silver Concentration
- Silver (Ag): 2,732 ppm
- Certified using multi-laboratory consensus methods including fire assay and instrumental techniques
- Certified values reported on appropriate sample bases depending on analytical method
This concentration makes the material well suited for:
- Mid-to-high range silver calibration checks
- Linearity validation between low-ppm and rich-ore Ag CRMs
- Drift and repeatability monitoring in Ag-bearing sulphide matrices
Typical Chemical Composition (Selected Major & Pathfinder Elements)
This CRM is a complex polymetallic sulfide concentrate, representative of real silver-bearing ores encountered in mining and processing environments.
| Element | Certified Value |
|---|---|
| Silver (Ag) | 2,732 ppm |
| Copper (Cu) | ~17.1 wt.% |
| Zinc (Zn) | ~18.4 wt.% |
| Lead (Pb) | ~8.0 wt.% |
| Gold (Au) | ~35 ppm |
| Iron (Fe) | ~17.1 wt.% |
| Sulfur (S) | ~28–30 wt.% |
Numerous additional trace and minor elements are characterized, making this CRM valuable for multi-element XRF verification and interference evaluation
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-rich polymetallic concentrate matrix
- Suitable for loose powder analysis, sample cups, or pressed pellets
- Excellent repeatability when handled according to standard XRF SOPs
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.
Typical Use Cases
- Silver ore & concentrate verification
- Precious-metal mining and exploration
- QA/QC programs for XRF instruments
- Cross-checking laboratory vs field results
- Training and method development
Important Handling & Storage Notes
- Fine powder – avoid inhalation and use appropriate PPE
- Store sealed in a dry, temperature-stable environment
- Do not dry prior to analysis unless required by your internal SOP
