Precious Metals

Precious metals testing for trade purchase, bulk supply, or repairs requires precision and care to ensure appropriate pricing, customer confidence and dealer reliability.

Niton precious metals testing instruments are ideal for precious metals testing, analysis, recovery and recycling. They have rapidly built a reputation in the precious metals sector as valuable tools for precious metals analysis and precious metal recovery and recycling.

Niton XRF instruments provide a fast, reliable, non-destructive means of identifying and quantifying the composition of precious metal alloys and can also be used to assess the quality and grade of metals such as silver, platinum and gold. As such, they are an essential tool for identifying unknown or unmarked items and being able to quantify their real value.

Key benefits include:

Non-destructive testing with instant results
Immediate identification for all grades of gold
Suitable for ingots, bars, chains, rings, etc
No acids required – The end of the acid test!

Niton precious metals analysers with precious metal calibration can detect a wide range of elements including: Au, Ag, Pt, Rh, Ru, Ir, Pd, Cu, Zn, Ni, Co, Fe*. They now include the very latest Thermo Scientific Niton AuDIT technology, a proprietary gold plating test and detection system.

AuDIT Test for Gold Plating Identification

Thermo Scientific Au Detection and Identification technology (AuDIT™) is a proprietary gold plating test and detection system developed for, and only available on, Thermo Scientific Niton portable XRF precious metal analysers, including the Niton XL2, XL2 100 and DXL.

For buyers of scrap jewellery, a gold plating test is essential as the presence of plating can adversely affect profitability. The AuDIT™ gold plating test meets this challenge accurately and easily, helping to save time and costs. Several independent complementary methods in the software work in tandem to alert the user to the probability that an item is plated.

Quickly Test For Gold Plate

The primary patent-pending technology is used as the first gold plate test which will work regardless of the gold concentration of the plated surface layer. If this test fails, ‘gold plate probable’ is displayed and highlighted on the screen and it is relatively certain that the items are gold plated.

Other tests are conducted simultaneously to warn users that something is ‘off’ in the analysis of the sample. These secondary tests will warn users only if the initial test passes. These tests include, but may not be limited to, the following:

High nickel (Ni) content, which can indicate presence of a Ni boundary layer between the substate and plated surface
Low karat values
Non-standard karat values (readings significantly different than 9, 10,14,18,11, 22 and 24 karat gold)
