Description
A 14k Rose Gold Certified Reference Material (CRM) designed specifically for handheld and benchtop X-ray fluorescence (XRF) spectrometry calibration and quality control.
ERM®-EB506 provides traceable, SI-certified mass fractions for Au, Ag, Cu, and Zn, making it ideal for precious metals verification, jewelry analysis, scrap gold sorting, and XRF performance validation.
Developed and certified by BAM (Germany) under the European Reference Materials (ERM) program.
For field verification and PMI work, many customers pair this material with NEW or PRE-OWNED handheld XRF analyzers for rapid, on-site analysis.
Certified Composition (Mass Fraction %)
| Element | Certified Value (%) | Expanded Uncertainty (k = 2.5) |
|---|---|---|
| Gold (Au) | 58.56 | ± 0.06 |
| Silver (Ag) | 3.90 | ± 0.05 |
| Copper (Cu) | 35.65 | ± 0.06 |
| Zinc (Zn) | 1.891 | ± 0.018 |
Values are traceable to the SI and represent the unweighted mean of accepted interlaboratory datasets
