How XRF works
An XRF analyzer fires X-rays at a sample. Each element emits a characteristic secondary X-ray, letting the instrument read precise composition without damaging the item — ideal for gold, platinum and karat verification.
Common uses in the jewelry trade
- Verifying karat and purity before purchase or resale.
- Detecting plating and surface treatments.
- Quality control in manufacturing and refining.
