X-Ray Fluorescence Testing

Utah Gold Buyer LLC offers NON-Destructive expert assaying services to customers who want to determine the types and quantities of different metals in an item. We use state-of-the art X-ray fluorescence analysis to determine the metal type (i.e. assaying) and percent of total.

We can identify elements of 26 different metals, including gold, silver, platinum, palladium, copper, zinc, nickel, cadmium, iron, maganese, and lead among many others. Whether you are a silver or gold buyer or seller, want to understand the value of some gold jewelry, or are trying to identify or validate the content of items you have found or had manufactured, Utah Gold Buyer can provide an accurate assessment of the metal content.  WE CAN NOT ASSAY ROCKS OR ORE that you may believe contain precious metals unless there are visible and larger sections containing metal.

If you would like cadmium or lead testing, our x-ray fluorescence testing is the same method/technology that many state agencies use to test toys and other items for lead or cadmium. However, we are not a licensed cadmium or lead tester and cannot provide official documentation.

Pricing for XRF analysis does not include the price of shipping should you send us your item and want it returned to you. Call us for details on returning a sample when you are not present for the test.

Metal Identification

Base Metals

In mining and economics, base metals refers to industrial non-ferrous metals excluding precious metals. These include copper, lead, nickel and zinc. The U.S. Customs and Border Protection is more inclusive in its definition. It includes, in addition to the four above, iron and steel, aluminum, tin, tungsten, molybdenum, tantalum, cobalt, bismuth, cadmium, titanium, zirconium, antimony, manganese, beryllium, chromium, germanium, vanadium, gallium, hafnium, indium, niobium, rhenium and thallium.

Precious Metals

A precious metal is a rare, naturally occurring metallic chemical element of high economic value. Chemically, the precious metals are less reactive than most elements. They are usually ductile and have a high luster. Historically, precious metals were important as currency but now are regarded mainly as investment and industrial commodities. The best-known precious metals are the coinage metals, gold and silver. While both have industrial uses, they are better known for their uses in art, jewelry, and coinage. Other precious metals include the platinum group metals: ruthenium, rhodium, palladium, osmium, iridium, and platinum, of which platinum is the most widely traded.
