Another type of precious metal analysis we offer is an ultrasound assay. A special machine sends an ultrasonic pulse through a sample and measures the frequency for changes. If the consistency of the metal changes, so does the frequency. This makes the ultrasound test perfect for determining whether an item is precious metal-plated without damaging it.
- Unlike other assay methods, melting is not required.
- Uses an ultrasonic pulse to measure changes in metal composition.
- Most useful for catching counterfeit bullion or sorting out precious metal plated items from solid ones.
While gold, silver, platinum, and palladium metals come from different industries and may be used for different applications, we have expertise with them all.
