XRF FAQs on Precious Metal Analysis
How do you test a precious metal?
XRF analyzers for precious metals test the sample material to determine the purity and composition of the precious metals contained within the sample. XRF is used across a range of industries to provide precious metal analysis in the field, in the lab, in the showroom, and on the manufacturing line.
How accurate is XRF gold testing?
XRF precious metal analyzers are widely regarded as one of the most dependable techniques for analyzing gold. The following table displays the accuracy and precision of XRF in gold and precious metal testing:
Vanta GX PIN model (15-second test time, %)
| Element | Test 1 | Test 2 | Test 3 | Test 4 | Test 5 | Vanta GX Average (%) | FLUXANA 0732-16 Certified Value (%) |
| Gold (Au) | 33.50 | 33.40 | 33.39 | 33.38 | 33.42 | 33.42 | 33.33 |
| Silver (Ag) | 58.30 | 58.41 | 58.36 | 58.29 | 58.41 | 58.36 | 58.61 |
| Copper (Cu) | 8.2 | 8.2 | 8.25 | 8.32 | 8.17 | 8.23 | 8.06 |
The table compares the results (percent of elements in the sample tested) from an XRF precious metal analyzer (Vanta GX PIN model) to certified reference standards for gold alloy jewelry.
