Gold & Precious Metal Analyzers
Non-destructive gold purity in seconds — XRF Si-Pin precision.
Lab-grade XRF (X-Ray Fluorescence) analyzers — Signet FSDD, Si-Pin and PC — for non-destructive gold karat testing, alloy verification, plating thickness measurement and full elemental analysis from Na (11) to U (92). Built for BIS hallmarking centers, banks, refineries and jewellery retailers.
Direct Answer
A gold XRF analyzer uses X-ray fluorescence to non-destructively measure the purity and elemental composition of gold, silver, platinum and other precious metals in 5–60 seconds with ±0.03% accuracy — without melting, scratching or chemicals.
