Can XRF Be Used to Test Silver or Platinum?

The direct answer is yes—XRF can be used not only to test gold, but also silver and platinum, along with other platinum group metals (PMG) like palladium and rhodium. By using advanced XRF analyzers, professionals can identify the purity and elemental composition of silver or platinum within seconds, without damaging the sample.This capability is particularly valuable in industries where verifying authenticity and quality is critical.

Why XRF Works for Silver and Platinum Testing

Unlike destructive testing methods that require cutting, filing, or using acids, XRF works by exposing the sample to an X-ray beam. Each element inside the material emits its own unique fluorescent X-ray signature. This allows the analyzer to determine exactly which elements are present, and in what proportion.

For silver and platinum, this means:

• Silver Purity Testing: XRF can quickly distinguish between sterling silver (92.5%), fine silver (99.9%), and silver alloys containing other metals such as copper or nickel. This is essential for both jewelry stores and recycling businesses.
• Platinum Purity Testing: Platinum is commonly mixed with other PMG metals such as palladium or rhodium. XRF can identify these alloying elements with high precision, ensuring accurate purity verification for both jewelry and industrial platinum products.

Because the process is non-destructive, the tested item—whether it’s a platinum ring, silver necklace, or industrial component—remains completely intact after analysis.

Real-World Scenarios Where XRF Adds Value

1. Jewelry Shops

Customers often want proof that their silver or platinum purchase matches the advertised purity. With an XRF analyzer, jewelers can provide instant, transparent results, building trust and avoiding disputes.

2. Precious Metal Recycling

Both silver and platinum are highly recyclable. Scrap dealers and recyclers need a reliable way to quickly determine metal content for pricing and sorting. XRF analyzers allow them to process large volumes efficiently.

3. Quality Inspection Institutions

Testing agencies rely on XRF for certification and quality control. For silver, it ensures products meet standard purity requirements. For platinum, it validates materials used in industrial applications such as catalysts or electronics.

4. Pawnshops and Collateral Businesses

Pawnshops face risks from counterfeit silver and misrepresented platinum jewelry. A portable or benchtop XRF analyzer provides immediate answers, protecting both the business and the customer.
