Precious metals require — and reward — careful analysis. But analysts face various difficulties. The scope of precious metals analysis extends from trace levels to 100%. Most of these metals are resistant to dissolution by all but the strongest acids. Some traditional analytical methods like fire assay are time-consuming and demand a high level of skill.

 

Three modern techniques offer widely used solutions. Energy-dispersive X-ray fluorescence (ED-XRF) and optical emission spectrometry (OES) can be used without specialist analytical training to rapidly and accurately analyze bullion, jewelry, and alloys. A variation of OES, inductively coupled plasma optical emission spectrometry (ICP-OES), is an ideal tool for the analysis of bulk materials such as ores, and for the determination of trace impurities.

 

Several instruments available from SPECTRO Analytical Instruments represent the state of the art in these techniques. This paper describes their application to precious metals analysis.

Application Brief: Precious Metals Testing with ED-XRF Spectrometry (XRF-115-AB)

 

Precious metals demand careful analysis. The high monetary value of gold and silver — as well as of the platinum-group metals platinum, iridium, palladium, osmium, rhodium, and ruthenium — means that purity is a prime consideration when trading in these metals, or in jewelry or other products made from them. The presence of other elements in minor or trace amounts can sometimes be difficult to detect but can have a dramatic effect on value.
 
Energy-dispersive X-ray fluorescence (ED-XRF) spectrometers are now the preferred means of analysis at many of these points. Instrument makers constantly seek to improve their designs. Better performance can make important differences in several of these applications. This paper examines the use of a recently redesigned XRF instrument.

            • Even better performance: Ideal for routine analysis and precise analysis of all incoming/outgoing materials and for process control (including nitrogen) in foundries – covering 10 matrices, 65 methods and 54 elements, at lower operating costs and minimal maintenance requirements

           

          The SPECTROMAXx stationary metal analyzer is used mainly for material testing in foundries and for incoming and outgoing inspections in the metal industry around the world. It determines all of the elements used in the metal industry, including metal analysis of carbon, phosphorous, sulfur and nitrogen.

           

          The eighth generation of the SPECTROMAXx arc spark OES metal analyzer comes with drastically reduced operating costs, significantly shorter measuring times and less maintenance requirements – while still offering exceptional precision and stability. And when it comes to productivity, the new SPECTROMAXx sets the benchmark.

           

          It features truly intuitive operation, with the use of toolbar buttons, a user management system, and a clear separation of operation from programming of the instrument. The measurement is controlled with clear symbols and toolbar buttons. Once a workflow has been started, only the functions that are logical at any point in time along the way are active in the control software – all other commands are hidden. With the new application profiles, customer specific information can be set before beginning operation, relieving laboratory technicians of administrative activities.

           

          The SPECTROMAXx arc/spark OES metal analyzer independently monitors all operating parameters. It dynamically determines the measurement time required based on the given sample properties and even shows when the spark stand needs to be cleaned depending on the type of samples being examined. The optional AMECARE machine-to-machine (M2M) support allows proactive alerts, backed up by direct connection with a remote SPECTRO service expert’s PC.
