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.

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

• Verification of silver detection in copper concentrates
• Field QA/QC checks for mining and metallurgical operations
• Drift and repeatability monitoring in sulphide-rich matrices

✔ Benchtop & Laboratory XRF Systems

• Method validation for copper concentrates
• QA/QC control charting
• Instrument-to-instrument comparison
• Training and analyst proficiency testing

Because this is a natural sulphide concentrate, its XRF response closely reflects real-world production samples.

Physical Form & Preparation

• Finely milled, homogeneous sulphide concentrate
• Copper-dominant polymetallic matrix
• Suitable for loose powder analysis, sample cups, or pressed pellets
• Prepared for consistent, repeatable XRF measurements

Why Use an Alloy Geek Certified Reference Material?

• Real-world copper sulphide concentrate matrix
• Certified silver at trace levels relevant to smelter and mine workflows
• Independently certified chemistry
• Excellent homogeneity for repeatable results
• Optimized for handheld and benchtop XRF analyzers

This CRM is an excellent low-Ag companion material within a broader silver QA/QC ladder.

Typical Use Cases

• Copper concentrate verification
• Silver tracking in polymetallic sulphide materials
• Mining and metallurgical QA/QC programs
