Description
Polymetallic Copper Concentrate CRM for XRF Verification & QA/QC
The Alloy Geek Copper Sulphide Concentrate Certified Reference Material – 145 ppm Ag is a certified, polymetallic sulphide concentrate designed for verification, validation, and routine quality control of handheld and benchtop XRF spectrometers.
This material represents a real copper concentrate matrix dominated by copper, iron, and sulphur, with silver present at a well-characterized trace level. It is ideal for users who need matrix-matched verification for copper concentrates, smelter feed, and polymetallic sulphide materials rather than synthetic or oxide-based standards.
Certified Silver Concentration
- Silver (Ag): 145 ppm
- Certified using multi-laboratory consensus analytical programs
- Suitable for low-to-mid range silver verification in copper-rich matrices
This concentration is ideal for:
- Verifying silver response in copper sulphide concentrates
- Bridging low-ppm silver CRMs with higher-grade silver ore materials
- Drift monitoring in polymetallic sulphide workflows
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 |
|---|---|
| Copper (Cu) | ~29.3 wt.% |
| Iron (Fe) | ~22–23 wt.% |
| Sulfur (S) | ~26–28 wt.% |
| Silver (Ag) | 145 ppm |
| Gold (Au) | ~9.5 ppm |
| Zinc (Zn) | ~1.17 wt.% |
| Lead (Pb) | ~0.14 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
✔ Handheld XRF Analyzers
